I tried to sync my iPhone library and my iTunes library on my computer, and it deleted a bunch of albums that I bought off iTunes on my phone. The first time I synced them, it worked perfectly and the albums from my phone transfered to my iTunes library without a problem, but the last couple times, several albums have been erased from my phone when I've been trying to sync them up. What is the problem? What am I doing wrong? How do I get the albums from my phone into my iTunes library on my computer? Is there anyway to get back the albums I lost?
