Alright, so here's the story: I don't know why my iTunes library does this, but sometimes when I add an mp3 file and close iTunes the whole library becomes corrupted and I need to manually add each song back into iTunes again, along with all apps and iPhone content. Basically, my iTunes library is totally screwed up right now. My iPhone is fine, completely unchanged. I did transfer purchases and back it up. But then there remains the issue of backing up to iCloud (although I just backed it up manually to iTunes as well). All I want is for my iTunes library to mirror that of my uncompromised iPhone. I have new mp3 songs I have in my library that I would like to add, but I am afraid if I sync it I will overwrite all my data on my iPhone. Please help, any suggestions are welcome. Thanks!
