will itunes match save space on my ipad?

iTunes Match allows you to listen to your songs from iCloud instead of having them stored on your device, so it may help you save space from your device. See > http://www.apple.com/itunes/itunes-match/

Note that you do not need iTunes Match if you purchased your songs in the iTunes Store. In this case, you can just delete them from your device and you will be able to listen to them from iCloud
