Are you kidding me?
Also Plastiware, what program do you use to make this sick music?
I don't like it when people ask me this question, because my methods for non-NES and non-SNES music are awkward and I do not recommend them. Mostly I use them because they are free and I am a cheapskate.
I start with a crappy free MIDI editor called Pianoroll Composer. The .mid I make with that gets loaded into Synthfont, and played with the SGM soundfont. I usually go back and forth between Pianoroll and Synthfont quite a few times before I achieve the instrumentation, volume levels, etc. that I'm happy with.
If you want to know more about how I made this specific piece, the MIDI instruments I used are slap bass, electric distortion guitar, electric clean guitar, drum kit ("power" drum set, plus some timbales for tropical flavor), steel drum, brass section, and harmonica.
