iTunes Match

What Is iTunes Match?
ITunes Match is a feature offered by Apple as part of its iCloud suite of web-based services. It allows you to upload your entire music library to your iCloud account, where you can then share it with other devices authorized to access your account. Now, instead of having to sync your iOS devices to your iTunes library each time you want to add music to them, you can just download the music from your iCloud account via iTunes Match.
