Songs on my iPad are magically being deleted
I took some songs from youtube, converted them into mp3s, added them to my iTunes library on my pc. Then, I synced the songs to my iPad so I could play around in garageband. They were fine yesterday, but when I checked today, all but one are gone! I can’t find them anywhere on my iPad. Explain, Apple, why songs are getting deleted from my library. This is unacceptable. If this is a bug in iTunes, FIX IT!
