I know there was a request for no Youtube links, so I'll try to add some MP3 download locations if I can, but they're rather difficult to find. I know they exist, but I haven't looked them up in years.
Battle Arena Toshinden (1):
This is only for one of the characters, but trust me, almost every piece is great. I won't post them all to avoid spamming unless requested, but the names of the characters are as follows:
Eiji *****
Kayin ****
Sophia ***
Fo *****
Rungo *****
Duke ****
Ellis ****
Mondo ***
Gaia ****
Sho ***
Goemon's Great Adventure (AKA Mystical Ninja 2: Starring Goemon)
I'd hand pick the best tracks, but honestly I'd be including about 80% of the soundtrack as some of the best. Only a few are duds.
Jetmoto 1 & 2
Nightmare
Much of the soundtracks of both games are very hit or miss, but Nightmare is a theme that has stuck with me for nearly two decades now.
