One of the most interesting features in Beats Music is that it creates custom playlists according to your tastes. This way, the more you use the app the more it learns about what music you like, and thus makes better recommendations. In the end, you'll have playlists 100 percent customized for you.
When you register on Beats Music for the first time you get 14 days of free trial. After that time you have to buy a subscription. This is a legal and paid service, and the fee is NOT higher than Spotify's.
Beats Music is an excellent music streaming service that lets you enjoy a gigantic music library. The interface is pretty and versatile, and lets you do any action with a tap or two on the screen.
