Everything was fine - but then today, I was trying to download a podcast (Inglourious Basterds podcast). The ipod went to sleep for a bit. When I opened it up again, and went to music, I saw for some reason an album flash, then when I went back to home screen, then back to music, all my songs and movies that were not purchased (everything NOT in the "purchased" playlist, plus my purchased podcasts were still there) were gone. I don't understand what happened, especially since the ipod still says that there's only 30 mbs left - with only 4 songs and 3 podcasts. Could anyone help me with this?
