I upgraded to the beta ios7 from ios6 and found that all 3000 of my hand picked songs from my iTunes Match (10,000 total) had been erased, I assumed iTunes match would work much like backing up app store apps in the sense that when you restore from a backup Apple will download all the apps you had automatically from the Apple Store again, why the heck can't iTunes match do the same? Now I must spend 2 hours muffling through my entire match library on my phone -_- download the certain tracks I want. Very bothersome.
