For me it's the curated playlists that make it great. IMO opinion they do a fantastic job. I've been getting more and more into Neil Young recently. I just opened Beats and they are showing me a Neil Young album I might like on the main page. I've also started listening to Albert King and they have an 'Intro to Albert King' playlist there too. It's a bit hit and miss but about 75% accurate. When I use Spotify I typically have to think of something I'd like to hear. I find their discovery page awful. When I open Beats I have an album or playlist that I like selected in a few seconds. It seems to be pretty good at learning my tastes and I'm also pretty happy that it's not just recommending similar stuff but a broad enough range of music that I'm expanding my horizons a bit.
