i just got my new mac, opened ituens , added my mp3 folder from my external HD, added it, but when i go to itunes via the remote control i get a message saying itunes cant play the songs and i have to click on them and purchase them in itunes. i have about 30gb of music, much off cd's. buying 30gb of music is out of the question. what can i do here? this issue, if not resolved will end in me returning my mac!
