does icloud back up my entire music library on my phone?
I am thinking about backing up my iphone 4 now because I am going to buy the Iphone 5. I have my entire music library on a back up hard drive that i can connect to my computer. However, this takes forever. Can I use Icloud to back up my entire music library on my phone so when I get the Iphone 5, I can just put the music on it very easily, or does it only back up "purchased" songs?
