I mainly listen to punk and it's extremely hard to find bands that are not on Tidal. When I migrated my playlists to Tidal from Spotify, there was only 1 Band which didn't exist on Tidal. But because it was only 1 song that was part of one of my playlists, I simply didn't care. ~~I don't even remember which one it was.~~ Aha, they're called Valentiine (3 piece all-girl garage rock band from Melbourne, Australia) and they're still not on Tidal. Still don't care.
Can't speak for Jazz though.
Good thing they are migrating to FLAC! Also, while MQA is objectively worse, subjectively it's pretty much equal to objectively better options. At least for us humans :) I found this double-blind test of MQA critic Archimago and they couldn't find a statistically significant difference between MQA and PCM :)
