My name is Skrillex, man! Welcome to the Devil's Den!
(Skrillex introduces himself to Mozart. "My Name Is Skrillex" is the name of his first EP (extended play), and "The Devil's Den" is another one of his notable songs.)
I'm a scary monster stomping this sprite in frilly pants!
(Skrillex made a song called "Scary Monsters and Nice Sprites", which is regarded as one of his most well-known songs. He states that he's the frightening monster while Mozart is the weak sprite who will be beaten in this battle. Sprites are typically considered as peaceful and silly beings, and therefore, figuratively speaking, are most incompetent for a showdown between such a terrifying foe as Skrillex. This line is also a taunt towards Mozart's classical dressing style due to the fact that men in his time period wore frilly pants.)
You're a weirdo, Wolfie! You're into powdered wigs and poop,
(Mozart's first name was Wolfgang, and Skrillex shortens it to Wolfie, a nickname he was given to him by his wife in his film, Amadeus. This is the English version of Mozart's childhood nickname, Wolferl. Wearing powdered wigs was popular in his time, and Mozart was known for his fondness of scatological humor, or an interest in feces, both in his personal life and in his music. Skrillex is pointing out that not all of Mozart's songs are prestigious and noteworthy.)
And your cousin blew notes on your little Magic Flute!
(The Magic Flute was one of Mozart's most famous compositions. To play the flute, you have to blow into the instrument and to blow someone means to suck their penis. Mozart was said to have fallen in love with his cousin, so in addition to his list of disturbing things, Skrillex says she sucked Mozart's dick, replacing the word with "magic flute", as well as calling his manhood little.)
Your daddy issues make the Jackson 5 look like the Family Circus!
(Mozart's father was very strict when it came to his son's talent for music. He would not let Wolfgang stop playing, and he made him play everywhere for everyone, similar to the Jackson 5, the pop band featuring Michael Jackson when he was young. Their father, Joseph Jackson, would make them practice non-stop until they perfected their music. Mozart had actually started his music career at a younger age than Michael did, who was six at the time he began singing. Skrillex thinks Mozart's dad was even harder on him than the Jacksons' dad, making them look like the family in The Family Circus in comparison, which is a comic strip about an apathetic family with no real problems.)
You might have been a genius, but you died baroque and worthless!
(Mozart was a genius from an early age, but he died penniless and of no importance. Baroque is a period of musical history that came around not long after Mozart, and he used some aspects from this period to create his own works. Baroque here is used to sound like "broke", which means to have no money.)
I'm rich, acclaimed and famous! I'm on playlists! I'm the A-List!
(Skrillex gains a lot of wealth for his music; he has a net worth of $16 million and earns $100,000 per show. Many people buy his songs and put his works on playlists. He is also an "A-list", or bankable, celebrity.)
You're the lamest! Kiss my ass, A-A-A-A-Amadeus!
(Skrillex says Mozart is an unappealing composer because classical music isn't a high point of interest in modern society. He tells Mozart to kiss his ass since he's getting beaten by him, though "kiss my ass" could also refer to "Leck Mich Im Arsch", a song composed by Mozart meaning "Lick Me In the Arse", which is one of his aforementioned poop-oriented songs. Amadeus was Mozart's middle name. Mentioning his name references the Falco song, "Rock Me Amadeus", which features a similar lyric, and the way Skrillex says it references sound effects in dubstep music.)
Was that a verse, or did you just get the hiccups?
(Mozart insults the stuttering part of Skrillex's verse, as he sounds like he had hiccups towards the end. Dubstep is often criticized for sounding like random noises or machines.)
I'm a prodigy, Sonny, and I'm about to smack a bitch up!
(Mozart was a child prodigy. Skrillex's real name is Sonny John Moore, but it can be used as a reference to how old people stereotypically call young people "sonny", as Mozart was 256 years old at the time of the battle, while Skrillex is in his twenties; even then, Mozart lived to be 35, which is still older than Skrillex when he was portrayed in the battle. Mozart says that he is going to beat him, both lyrically and physically. This line could also reference British group The Prodigy and their hit song "Smack My Bitch Up".)
My music is 200 years old, and it's still excellent!
(Mozart died over two centuries ago, and his music is still regarded as being among the best compositions ever.)
In two more months, the world will forget about your Skrill-excrement!
(While Mozart's songs will live on for generations, modern music now normally has a lifetime of a couple of months, meaning Skrillex's music will be forgotten by then. Skrillex's name is combined with the word "excrement", a technical term for feces. He also says that Skrillex's music is bad, which is another reason it won't be memorable. Mozart's mention of excrement is likely another reference to his interest in feces.)
I can't believe the way you dress when you dubstep out of the house!
(Mozart is appalled at Skrillex's clothing and hairstyle because it's different from what someone would normally wear out in public. Mozart replaces "step" with "dubstep", house music and dubstep being the two main genres Skrillex's music falls into.)
You're like an emo Steve Urkel, and you (ooh!) reek of dead mouse!
(Steve Urkel is a fictional character from Family Matters, made to seem annoying and dress strangely. Since Skrillex wears glasses similar to Urkel, he appears to be the emo version of him. Deadmau5 (pronounced "dead mouse") is Skrillex's friend, a Canadian electro house artist. Mozart says Skrillex and his music stinks like a dead mouse, which can also imply Skrillex copied deadmau5.)
I am the world's greatest composer! No one knows what you are,
(Mozart is considered one of the greatest composers in history. Skrillex, on the other hand, wasn't very familiar with some people on the day the battle launched and thus, they had no clue who he was. Although Skrillex is currently well-known, he probably won't be remembered much in the next couple of years, as well as most modern musicians and composers. In short, the latter sentence is there simply to relate with people who never heard of Skrillex beforehand.)
Except a lonely little troll who knows how to press a space bar!
(Mozart's insulting the fact that Skrillex's music is computer-generated. Some software of its kind uses only about two buttons, the left-click and space bar. Skrillex is also called a troll, a slang term for hater on the internet, meaning that he's just throwing petty insults at him. The space bar is also the button usually used as the play button for a lot of software, meaning that Mozart is suggesting all Skrillex has to do at a live concert is press play.)
I attack! You decay! Can't sustain my releases!
(Skrillex's music makes him look larger than life. He is also active, as Mozart is dead and decaying, so Mozart cannot withstand the music Skrillex creates. Attack, decay, sustain, and release are four of the main parameters in sound synthesizers.)
Sidechain, Wolfgang! Bangarang you to pieces!
(Sidechaining Compression is a technique used in many sub-genres of electronic music. Sidechaining allows multiple instruments to be placed on the same frequency without clashing or peaking by compressing the sidechained sounds when they play at the same time, resulting in a more professionally sounding track. Wolfgang is Mozart's first name, the same as another dubstep artist Skrillex works with, Wolfgang Gartner. "Bangarang" is one of Skrillex's most famous songs. Skrillex is hinting that he's going to tie Mozart up and rip him to pieces.)
I'm a self-made man. You're a slave to your papa!
(Skrillex worked his way to fame on his own. Mozart, however, was forced into music by his father, who (as previously mentioned) took control of Mozart so he could become famous for his music.)
I'm a r-r-rock star, mix you with the bass and drop ya!
(Skillex's musical career started in a rock and roll band called From First To Last. After he worked solo, he later produced a song called "Rock n' Roll (Will Take You to the Mountain)". The word "rock star" is stuttered to imitate dubstep, like Skrillex used at the end of his first verse. In dubstep, "bass drops" happen when the beat kicks into overdrive after a lull in the song. He implies he'll both drop the bass and put Mozart in with it, causing him to drop as well. When Skrillex says "drop ya", the bass has been dropped, and so his voice drops several octaves in that instant. It was done to spoof the real effect of bass-dropping: that a song's percussion gets amplified, becoming more powerful.)
Global! My strobes glow like Chernobyl!
(Skrillex is known internationally for his music. Strobe lights are light fixtures that cast a pulsing light, often seen at raves and dance clubs, which dubstep music is often played at. Chernobyl was a nuclear disaster in Ukraine from the 1980s that caused radiation through the entire area. Skrillex says his lights shine at an intense rate.)
Kids explode and get mobile! No one even knows you!
(Nowadays, artists like Skrillex appeal to modern youth because his music is the kind to which teens would listen to and download to their phones. Due to this, Mozart's works are no longer remembered by younger generations to the point that kids don't even know who he is.)
I make the whole world move! You play community theatre!
(Skrillex's music makes people around the world want to dance to the beat, and he plays in international shows. Mozart played his compositions in community theaters, so Skrillex insults him for being known only in a small area.)
I gained your same fame from home on a blown out speaker!
(Skrillex started out his career at home with a dysfunctioning speaker. Eventually, he became just as well-known as he is today, as Mozart was in his time. A speaker can also blow out if the music is too loud, and Skrillex's music is known to have high volumes.)
Oh yes, I've heard that EP, and see, I transcribed it here.
(To transcribe a song means to list all the instrumental notes. Mozart was able to listen to a song once and transcribe the music from memory, as he just did with Skrillex's songs. An EP is an acronym for extended play, which Skrillex has.)
Tell me, what comes after the 68th measure of diarrhea?
(After noting Skrillex's music, he finds it to be a sloppy piece of crap, like diarrhea. The music drags on for a while, being over 68 measures long.)
And what kind of drugs does it take to enjoy this? I've no idea!
(Mozart thinks that Skrillex's songs can't be appreciated even if you take drugs while listening to it.)
I've seen more complexity in a couch from IKEA!
(IKEA is a large furniture store, originally from Sweden. After buying furniture, you must put it together on your own, following instructions. Some of these are simple to assemble, but Mozart says they're more complex than Skrillex music, which must not be very complicated at all.)
You go piano to fortississimo!
("Piano" and "forte" are dynamics in musical notation meaning "soft" and "hard/loud" respectively, and "issimo" is added to them to mean "very" (pianissimo "very soft"/fortissimo "very hard"). Mozart uses this to tell Skrillex his music starts at a low volume, and it later becomes extremely loud. A common tactic in dubstep songs is to lower the sound levels so the listener thinks the song is almost over as the track nears the end, and then startle or surprise them by quickly increasing the volume to an extreme level.)
That means soft to very, very loud, 'cause I'm guessing that you didn't know!
(These are basic key words known by all classical musicians, meaning that if Skrillex doesn't know something as simple as that, Mozart claiming he doesn't, then he doesn't know much about composing.)
Why don't you put down your Cubase and pick up a real bow?
(Cubase is a system used to make dubstep tracks, most likely used by Skrillex. He is being told to use a commercially acceptable musical instrument rather than use a computer to make music. While saying this, Mozart also takes out a bass and a bow, demonstrating what musical instruments back in his time look like.)
I rocked harder than you when I was 5 years old!
(Mozart learned to compose at the very young age of five. He finishes the battle by saying he made better music than Skrillex when he was only a kid. Also, because of his fame at the time, Mozart is considered by some to be one of the first "rock stars" ever.)
