Ok i am about to Format my PC to clean it and i am just gonna back up my original music folder and i had some questions. Backing up my original music folder will keep album art, lyrics and changes to names and info of the songs made in itunes? What i need to do to keep all these? I tranfer my huge music collection to my iphone checking the boxes on itunes to select only those songs i want in? after formatting is there a way to keep those selected without me have to re check every song i want? After format and reinstalling Itunes again, how to make sure i dont lose contacts or anything in my phone? how i tell the new formatted pc to keep all the stuff on my iphone? Thanks!
