Downloaded songs not showing on iPhone or iTunes
Recently downloaded an album from iTunes using my iPhone 4 using iOS 7, worked fine for a while then my iPhone started randomly removing songs and made them available to download from the iCloud.
* I have my iPhone backed up to my computer (not to the cloud), files for the songs are not showing up in my library on my computer's harddrive.
* I've tried syncing my iPhone to my iTunes, it does not recognize that the songs are in my library or in my "Purchase" playlist.
* Looked on the iTunes store and it shows the album is purchased, but won't allow me to re-download it.
This has happened with multiple albums, I just noticed because this is a fairly new purchase (within the past 2 weeks) and I enjoy listening to it. I've had this iPhone for 2.5 years now and have never had many issues till I downloaded iOS 7.
Any help or suggestions on recovering "lost" albums would be appreciated.
iPhone 4, iOS 7.0.3
