In my case, Tidal has created seven "My Mix" old school R&B and contemporary Jazz playlists that contain some of the music in Tidal playlists that I've created; additional music that I've heard or have not in a Tidal playlist; and some new music songs. Tidal Radio is also good for finding new music, but sometimes it is hit or miss for a song that I like.
Your method for discovering great music.
I'm in a slump. It has been a while since I've discovered new music that I really like. And when I say "new" I mean new to me. Maybe even rediscovered would count as new.
I do not have a method. I usually stumble into new music that I like. I also don't have loads of hours to sort through tons of stuff I don't like. Plus I find that random sort of pursuit to be frustrating and unrewarding most of the time.
Amazon Music had half decent 'recommended for you' lists but I don't recall if that ever paid off. I use Qobuz now which sucks in that particular department.
I've found a few bands that I like from recommendations here at Audiogon but I have not been here much lately.
So I'm curious as to how some of you approach that search for great music that is either actually new, new to you or rediscovered.
