“45 million songs. Three months on us….” This is what Apple says on its website, claiming that 45 million songs are available on Apple Music. However, you can only have three-month trial. That being said, you must pay for songs you want to listen to after three-month free trial. Worse than that, music tracks in Apple Music library are protected by Digital Right Management policy, which is employed to restrict the use, modification, and distribution of proprietary copyrighted works, especially music. Due to DRM restriction, you cannot make full use of purchased Apple music, such as setting purchased Apple music as iMovie background music or turning purchased music as iPhone ringtone. Additionally, you cannot stream the purchased Apple music in non-Apple devices.
