I listen to music the most in bed so that's when most of the discovery happens and Tidal and Bandcamp are my platforms of choice, thinking of dropping Spotify.

On Bandcamp I'll look at artists that have worked with artists I know I enjoy as well as their production companies.

When I'm using Tidal, I'll have a playlist full of stuff I like, make an empty playlist, add things to the new playlist that I'm thinking of adding to the old one, listen to and modify it until I feel like I enjoy the playlist, and then merge the two.

Once it hits like 500 I do a little cleaning, keep the favorites from particular artists, and look for other stuff to add.

Pretty much only use Tidal for ambient/experimental electronic music so theres plenty of stuff to rummage through.
