I purchased an album on Itunes. All but one song downloaded fine, but I can't get that one off of the cloud. Of course, that is the specific song that I need to download, so I can put it into an app that will slow it down so I can learn how to play it on the guitar. The song will play on my PC, but not on my phone. When I press the cloud icon on the phone, it goes into an endless loop of trying to download. I tried re-synching with my PC. Any suggestions?
