Imagine thinking recomendations can be objectively better than others. Personally I don't care for pandora recommendations one bit and love my spotify mixes.
1. Spotify
2. Pandora
3. No matter what, rickroll you on the next song
Cleary 3 is far superior to the other two! ;)
So if something can be objectively WORSE, there must be the possibility of something being objectively better.
