Using a freeware tracker that emulates the Sega Genesis/Mega Drive soundchip:http://shiru.untergrund.net/software.shtml
All there, free for download (click on image to go to album page).
Nearly 20 minutes of FM/Mega-Drive music. Many tracks not listed in the OP are found here.
If you want a .zip, look no further!

^^this one has got almost a Celtic feel to it, i dunno. I like Celtic :p
But yeah, download or listen, or something.
The tracker is a really cool program that I recommend aficionados of 16bit music to pick up and experiment around with. It's good stuff.
The link in my sig has my newgrounds page. Now, newgrounds sucks a whole lotta dick, but hey, it's somewhere to put my music... though i should probably get a soundcloud or something.
I also do SNES-style, 8bit, and occasionally, ambient, funk, and classical :-p
Sorry to clog the board with another "My Music" topic.
