A bunch of Capcom video game soundtracks have just found their way to Spotify today. Although the soundtracks are mostly listed in Japanese, they are available for streaming in North America right now save for some notable exceptions.
The soundtracks are all listed under Capcom Sound Team, and include soundtracks for games like Monster Hunter, Mega Man, Street Fighter, Ace Attorney, and more. Capcom is one of the few Japanese developers putting their soundtracks on Spotify while most western developers have their video game OSTs on the streaming service.
You can find soundtracks for recent games like Mega Man 11, but there are also soundtracks for unreleased Capcom games like for the various Japan-only Ace Attorney spinoffs that never got localized. There's an extensive library of music from Monster Hunter, Okami, and Devil May Cry, as well as music from older games like Breath of Fire 2. No Resident Evil soundtracks though, so that's a bit disappointing.
While it's sometimes painful seeing the soundtrack for a game like Ace Attorney Investigations 2, which was never released stateside, this is still a massive collection of good music. If you have a Spotify account, you can search for 'Capcom Sound Team' and access the full library of soundtracks. You can also search for individual albums, but since they're listed in Japanese, you'll need to search in Japanese also.
