1. After your initial upload is complete to iCloud, does your music need to remain in iTunes? Can you simply delete it all and then just add new music to iTunes when desired to sync with iCloud? 2. This is on the Apple site: Syncing music with iTunes will be disabled while iTunes Match is enabled on your iOS device. This confuses me. So if I have iTunes Match enabled on an iDevice, how can I upload new music to iCloud after the initial upload?
