So I've been using iTunes Match since it came out and a new recurring problem has come up in iOS7. The music app will randomly duplicate all the songs I downloaded by having a second version with the cloud indicator. For example, I'll download an album and then a day or two later the album will double in size because there will be a second version of each song with a cloud icon. The only way I've been able to fix it is turning iTunes Match off, restarting the phone and turning it back on. Has anyone else encountered this problem? Thanks!
