iTunes Match
An annual subscription that safely stores all your music in iCloud—even songs imported from other sources and not purchased in the iTunes Store—and makes it available on up to 10 of your devices and computers.
To use iTunes Match, be sure you turn on iCloud Music Library on all the computers and devices where you want to use it. If you subscribe to Apple Music, you don’t need to subscribe to iTunes Match unless you still need to access your music on an Apple TV (2nd or 3rd generation).
