By request of a few people, I decided to make a Megaman X music wad (http://www.mediafire.com/?159r5k3yg8a7j9s). I apologize for the fact that the songs don't loop they way they should (The song will fade after awhile but start back up again from the beginning), but I couldn't do that without making it sound strange, like bits of the song were cut off if I tried it.
List of songs:
MMXOCTO - Launch Octopus
MMXSTIN - Sting Chameleon
MMXPENG - Chill Penguin
MMXMAM - Flame Mammoth
MMXKUWA - Boomer Kuwanger
MMXEAGL - Storm Eagle
MMXARM - Armored Armadillo
MMXMAND - Spark Mandrill
MMXSIG1 - Sigma Stage 1
MMXSIG2 - Sigma Stage 2
MMXSIG3 - Sigma Stage 3
MMXSIG4 - Sigma Stage 4
MMX1ZERO - Zero's Theme
MMXBOSS - Boss theme
MMXFB1 - Sigma Battle 1
MMXFB2 - Sigma Battle 2
MMXOPEN - Opening Stage Theme
MMXVILE - Vile Battle
Oh, and a couple of hidden songs too ;)
EDIT: Doh, had Mandrill's codename listed wrong. It's fixed now.
