This is all going to be "great gameplay" rather than "great story".
If you have a way to play 3DS games and a tolerance for punishment in your JRPG dungeon crawlers, the Etrian Odyssey series has some of Yuzo Koshiro's best work.
Finally ... Monster Hunter is an incredibly fun and addictive game series, and though it doesn't center the music quite as much as a typical JRPG does, it's got some great stuff. I particularly like the soundtrack of MH: World -- although the newer game MH: Rise tried something new with its mostly choral arrangements, I think they are not quite as memorable overall.
Arena battle from Monster Hunter: World (it's particularly impressive the way this theme, the small-monsters arena battle theme, and several of the town themes reuse the same melodies in different arrangements)
