I haven’t used Spotify in years but back then I was getting annoyed at their recommendations/generated playlists. Instead of new music I liked they just create 4 playlists of music I already have in my own playlists or music I don’t like at all and not even similar to music I listen to. I tried Apple Music for free because of a device purchase and their generated playlists actually gave me new music that I liked. Haven’t looked back since
Very. Not saying that I need them to be extremely intelligent, but should be at/around the same level as me, and have similar interests as me. Otherwise conversations would be more difficult?
