how do i put my music on icloud
Currently, my music, (roughly 7 GB), is all on my devices, a MacBook Pro, iPad 2 and iPhone 5. I want to free up space in all of these devices. I have plenty of free space in iCould, but can't seem to move my music there. I've purchase iMatch, in hopes that I could move everything using that. Thus far, no luck. Please help & give me clear step-by-step guidance, if possible, as I've tried several options already. Thanks!
