For the uninitiated, chiptune music is basically the 8-bit music from your childhood Nintendo Entertainment System. There is even a festival that showcases prominent chiptune composers and performers. Anamanaguchi and Nullsleep are a couple of the more popular chiptune groups out there.
For some reason, as chiptune music became more and more popular, it started showing up in other genres of music. None more disturbing than the chiptune arrangements of classical music. On that note, I give you chiptune Beethoven. You have been warned.
