I'm not very fond of orchestral/classical sountracks, so my picks exclude most of the popular picks like the Final Fantasy ones, and such. Also, I'm sure there are lots of great soundtracks out ther that I've not listened to, so these are my personal choices, more than the absolute best OST ever. Anyway, my choices are:
- Shenmue I & II (the Asian flavour overcomes my general dislike of 'classical' soundtracks with this one. II is less atmospheric than I, but more varied and better to listen separately)
- Streets of Rage I & II (I respect SOR3's soundtrack, it was a more daring approach to hard techno, but it's not as appealing to me as the previous ones).
- Jet Set Radio, Jet Set Radio Future and Ollie King (composed mainly by Hideki Naganuma, with some other contributions of the same quality by Deavid Soul, Latch Brothers, and other bands)
- Revenge of Shinobi & Shinobi III [Genesis] (the first was made by Yuzo Koshiro and is great, the second was not and, surprisingly, is just as good, a little less varied but more cohesive).
- Other honorable mentions: Castle of Illusion, Quackshot, Ristar, Kururin Paradise, Radiant Silvergun, Katamary Damacy, Napple Tale, Tekken Tag Tournament, Rez, Megaman & Bass .
