Apple Music. Not to be confused with Apple Records. Apple Music is a music-streaming service, developed by Apple Inc. Users select music to stream to their device on-demand, or they can listen to existing, curated playlists.
Like other music streaming services, Apple Music lets you play music that you haven't purchased by streaming it over the Internet. For the monthly fee, you get access to 30 million songs from the iTunes catalog (the entire catalog boasts 43 million tracks worldwide).
