Beats 1 is diverse in terms of different forms of hip-hop across the world mainly. Other than that it usually Top Pop tracks from around the world... which is all well and good, but they really fail to cater to jazz fans, folkies, blues, etc.; the selection of blues and jazz artists are very limited in the non-beats sections of Apple Music. Tried to listen to Magic Sam's "West Side Soul" album the other day... only 3 of the tracks from the entire album are available... period. Go to Spotify however, a totally different story - full album and a great catalog of his work.
While Apple Music does have exclusive artists like Taylor Swift, along with exclusive music only made for Apple Music, it's really not enough to tip the scales to pay 10 bucks a month for a service that screws up my Album Artwork, has a horrible selection of music to stream, and bloats my current install of iTunes on my Mac. Add in the fact they took away Genius Mixes in iOS 8.4, and that takes the cake for the reason I am annoyed with this current venture by the tech giant.
