Went to use my Touch the other day, and was surprised to discover there was no music under the music menu. I tried the video menu and same thing; I got the screen that says there's no content but you can get it from the ITMS, etc. All my photos, contacts, calendar, etc were ok. I opened the 'About' screen under 'Settings' --> 'General', and it said zero songs and zero videos, but my 'Available' memory indicated they were still taking up space (I had only 2Gb of 32Gb available). I tried rebooting, but no help. Eventually had to restore through iTunes and re-sync. That fixed the problem, but left me wondering. Happened to anyone else?
