cvs2 had a good sound track. the ret of the games not so much sfv had a better sound track then sf3 and mvc3 sfiv was good on some track. but better then doa6 and 5.
My favorite Capcom FG OSTs have always been SF2-SSF2T (of course) and SFEX+A (ok, you can argue that's Arika's work, but still). The CPS2 games like MsH to MvC and the Darkstalkers series had good music too. Some OSTs grew on me like SFA2's, SFA3's (half that soundtrack is epic for me now), and SS3TS's. Nothings been that memorable to me the past 15 years, not even in my fave recent Capcom fighters like MvC3 and TvC.
