OK, I need some help. I have an entire music collection imported into itunes. all the mp3s are categorized in folders by artist then by album. I needed to rebuild the library so i deleted them from itunes. I accidentally hit "move to trash" in the process. Now, All my music is in the trash and the "undo" option is grayed out. How can i pull all these music tracks back into their proper folders?? Pleas help, as this would be a nightmarish process to put all these loose files back into the proper folders.
