So far I’ve found everything I looked for, and a few new ones too. Their app features for lyrics and other songs you might like work great. Admittedly, I’m an old metal head who loves singing to a song at the top of the voice, out of tune of course, so I might not be skirting the kinds of niches you like.

I find there are a few niche artists/songs that arnt on tidal, but it still had a majority as well as some new options of the same genre

Imo spotify had way better playlists (a lot of specific user created ones are great) but u can just transfer the playlist to tidal with a site

I was using tidal and spotify for a bit, as tidal works with my dj software, but they just added a new pay teir for using it for those softwares :/

Overall i still used spotify more than tidal but i didn't have a bad time on tidal
