I lost all of my songs on iTunes and how do I get them back?

I pressed the auto full button and I was looking at the songs on my iPhone. The playlist that I was using to autofill was empty and now my music list is empty!

If you have ever went on the computer and saved your songs onto the iTunes application they will be there otherwise they are probably gone, I'm sorry for your lose.

If you used iTunes on a computer, just plug it in a sync again to put them all back on there again. If you haven't, I'm guessing you got them all from the iTunes store. In this case, go to iTunes>Downloads>Purchased and re-download them all.

  • Lost all my contacts, messages, and pictures on my iPhone, can I get it back? I got a new iPhone for Christmas and haven't synced it at all with the iTunes on my computer until now. When I synced it, it asked if I wanted to restore the information from my iPod, or start it as a new iPhone. I thought the restore option would just carry over all my songs, but now I've lost all my contacts, messages, and pictures I had on my iPhone and it looks exactly like my iPod does. Is there any way to fix this?
  • If I download songs to my IPhone and uninstall them, do I have to buy them again? The problem is I bought some songs but now I want to delete them so I can put some fresh new songs but I still want the songs for my IPod. So if I delete them from my IPhone, will I have to buy them again? More information will be added if needed, thanks in advance, hope I explained it right.
