The new one has more game music than old ones did. But to get a lot of it you have to subscribe. Thankfully the subscription isn’t terribly expensive ($10/3mo) and it’s easy to get it in a way that doesn’t auto renew. Music licensing is stupid though so music games are dying and will probably forever be subscription services going forward. The days of buying a game like guitar hero are long gone.

It has the classic ones like Mario medley, Zelda overworld, Kirby, persona 5, undertale, etc. but the game pass adds stuff like tekken, id@lmaster, ridge racer, tales of symphonia, ace combat, etc.

it’s a weird mix that’s definitely missing a lot of iconic stuff though. The push is definitely more pop/vocaloid/anime music

Alternatively you can get something like opentaiko or tjaplayer (closer to the real game) and use custom charts from a site like https://ese.tjadataba.se/ESE/ESE . You need a pc but it doesn’t require a particularly great pc and pretty much every drum controller, including the official console ones, work on pc.

I definitely wish it was more popular in the west. Online play is an absolute ghost town unless you play during Japan time. Like if you play during peak us hours matchmaking will literally spend 20-30 minutes to find no one.
