How to get my iTunes music back?

I cracked my iPhone 4S so I backed it up to iCloud and got a new one but when I restored backup on the new one I have no music

It is easy to recover notes from iPhone devices if you have previous iTunes backup files. You can simply restore from backup files via iTunes. But it will delete any media tracks currently existing on your iPhone and will overwrite contents on the iPhone with the contents from the iOS backup file. Or you can use iPhone Data Recovery to recover lost notes from iPhone device without any defects.
