I was cleaning up some folders when by accident I moved the entire folder to a new location, I restored it and went to put some new music on but to my dismay it says my library was empty. I dragged the entire folder back onto iTunes but its a mess with the tags. Is there a way to restore the library on my phone to iTunes? Its the music I want with all the tags edited properly.

I realized that after I did this there was an iTunes folder that had my library and I think its the one with the backup? Anyway is there a way to just get it from my phone to the program and just add music like before?
