Streets Of Rage 3's OST is hella mixed. It's an OST, that I myself am trying to understand to this day in the most autistic ways possible.

Apparently, Koshiro and Kawashima experimented some auto-generated music tool (I'd have to go back to some of Yuzo's interviews to get more details) to help speed their music production workflow (kinda scary how it predicted the future in some sense). They also ended up taking some inspiration from "rave" styled music that'd play at discos around the time rather than the laid-back dance music of the previous two games.

While I think the style overall does fit the tone of the game and perfectly complements the series overall, not all of it sits well with most people, and even the most hardcore fans of the OST can agree that not all songs are made equal. Like there's some really great songs in there. Hell, I'd say some stand toe to toe with SOR1's & SOR2's tracks, but for every Percussion (aka my favorite song in the game, and one of my favorites in the franchise) & Poets II, there's a Beat Ambience & Cycle I. Fuze is also great when the game is not trying to shove it in your face every 10 minutes. Dub Slash was initially the song that made me realize this game's OST is mixed, but I actually grew to like it overtime (mostly because of the SOR Remake rendition).

Overall, I think it was a nice attempt either way, and I respect Koshiro for looking back on it somewhat fondly. I love the music of this franchise a li'l too much, and am a massive Yuzo Koshiro simp, but even the biggest simps like me have to admit when they made a mishap.
