Spotify sucks too with this. Theres certain artists where if I create a radio station from a song/album or whatever, I will know what like 20 of those songs in that generated station will be. Maybe 8-15 artists and the same 1-3 songs they pick from that artist for that given sort of radio generated call. The feature is good for a toe dip into discovery but you hit the bottom of its depth almost immediately. Sometimes it changes the generated playlist, but hardly. Feels way more siloed than actual FM radio. I might have to start building my own playlists again and do old fashioned discovery, which was almost a part time job evaluating discographies and studying genre history.
