MANAGING YOUR MUSIC WITH ITUNES
You likely have a large collection of music files. The challenge, of course, is to have access to all your favorite music without taking up all the storage on your device.
You'll find that iTunes offers two solutions: selectively sync songs or playlists to your device or use iTunes Match to upload your music to iCloud so that your entire collection is available on all your devices. If you opt for the former, you can first create playlists in the iTunes software on your computer.
