Pre-ordered Coldplay's new album. Turned on my computer and opened iTunes, and songs started downloading - but only SOME of them. Other songs say "purchased" (which I had NOT purchased as singles...that's important), but won't download. If I looked at purchased music, those "purchased" songs are not there....only the ones that downloaded show up. I can't figure out a way to download them. Any ideas? Sorry in advance if I'm overlooking something obvious.
