Spotify was OK back when I used it after Google Music died. YouTube Music's algorithm sucked so I used Spotify for about a year. Then I installed Plex for movies and TV but also found it was also great at streaming music. PlexAmp gives me access to a good suggestion algorithm. I made the decision to give them my $$ instead.
Now with lidarr+scripts I can have any music I want with almost zero effort. Plus, as the OP said, I get the fun little side hobby of music curation.
