I uploaded 20gb of music onto my new mac, and now i have a folder for 'my music'. but when i try to drag/copy/add that folder to my itunes library, it seems to duplicate the songs so that it doubles up on my memory. Basically, you can find the music in the I-tunes library and in 'my music.' This happened when I first transferred my music from my PC. I only transferred 27 gigs, but it took up double the space. I found the other folder that it was in and deleted it, but now it happens every time i add more music... any suggestions? thanks.
