I disagree.

I don't necessarily know about new music, artists, or genres. I want to get a mixture of stuff I haven't encountered.

Something like 60% of the music I listen to in a given month I had never heard of 12 months prior. I've found so much music that I vibe with by way of generated playlists.

Discovering something new that scratches my music itch is in itself a pleasure for me, and I can go back to it at a later date, like everything else.

This doesn't mean I support Spotify, but it does mean I disagree with your stance.
