All I can tell you is that in my Mac iTunes library, almost every song and album from RUSH (and most other old CD's) had a cloud next to it. I looked up the icon here
http://support.apple.com/kb/TS4124?viewlocale=en_US&locale=en_US and it said it's in a "waiting" status. Well, I'd been waiting almost a week. So while I was waiting, those songs and albums were not available to me on the iPhone. RUSH is like caffeine to me: I need it in the morning to get me going. The boys can still bring it. Fortunately, their last two albums were available for download, but that's because they weren't remastered. But that's all I was able to listen to. Since I turned off iTunes Match, I've been able to sync the iPhone with my Mac library and all is well again. Apple did agree to the refund though, so I'm happy I'm not out any money. I'll give it another try when I know these kind of issues have been resolved.
