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.
