So I am a big Nerdcore junkie. Loving video game music and Nerdcore music. As of such, I have a LOT of 8-bit Chiptune music in my iTunes library. But I also have music that would be considered 16-bit, like SNES Game OTS and what not. 

I know that 8-bit music is referred to as 'Chiptune', or sometimes, 'Chipmusic' as the title of the genre. But I'm trying to figure out what I should put as the genre for my 16-bit music songs. Google isn't of much help with the search, and then I stumbled across this site. Figured I'd ask here! What genre is 16-bit music called? Like how 8-bit is 'Chiptune'.   

Is it MIDI? Or is a MIDI something different? What do I call it?
