It has a greater catalogue of “old” music: 50 ' s to 90 ' s, Apple Music concentrates solely in new developments. I like more to have the classic ones, and many complete discographies (although they lack some).
Compatible with old devices, until iPhone 3GS (lately with some problem). Apple demands last version of everything, beginning by model of computer and devices.
Very many better design than the one of Apple. Very easy to use. As much in devices as in mac, it works better and more clearly. Apple demands several clicks to be able to listen in album.And not always it is possible to listen to a complete CD. Better connections with related artists. More options and better selected. Four or the five you Apple only gives that everybody relates,and so you do not discover really new artists. In Spotify, it is on the contrary, very abierto, many relations and a world of new developments. As much noveles as already consecrated. Impressive.
