I find that it’s really easy to find new artists and albums I like on Bandcamp. I just started by following a few genres and listen to a some music at random. If I like it I add it to my whislist and carry on. And I just listen to the “new and hot” section. Gives way better results and more variety than Spotify ever did for me.
From time to time I go to my whislist and listen to some of it again and usually decide to either buy the album or delete it from my whislist.
I also use Qobuz for more mainstream artists that’s not on Bandcamp.
Recently started to put all my purchases into Jellyfin for easier management between the services.
I also have a few pirated playlists of my favorite songs from years ago. I go through them when I have time and money and see if I like the songs enough to buy some albums or songs from the artists.
