a few songs I have purchased on apple tv won't sync to itunes on my mac. they are in the songs section of the apple tv, but not the purchased on apple tv part of apple tv. can anyone help? also, when using itunes and locating the songs under devices - apple tv - music, I right click to get info, and they are checkmarked as compilations, but I cannot unclick it because it is greyed out. not sure if that is the problem or not. I appretiate any help I can get.
