RPGs with music in the mechanics

I bring up music in my RPG thinking pretty often, mostly to set mood but also lyrics providing ideas and bands as PC groups, but some RPGs use music as part of the system.

This RPGnet thread looking for examples brought up some I didn’t know. I myself mentioned VOID 1680 AM, a solo journalling game where you play a late night DJ and compile a playlist, and on the other end of the interactivity level LARPs based on musicals that can include performing, which sounds like one of the rooms in my personal Hell but I have friends who’ve played and run them.
