I have all of my music on my external hard drive. I just got a new pc and need to transfer the music into itunes. In the past I thought I could just drag and drop the folder but it is not working now, an X comes up on my cursor. The only other way I can get my music into my itunes library is to physically play it, I don't want to play over 2000 songs. What could I do? Thank you very much.
