I just purchased an Airport Extreme Base Station (AEBS). I have most of my music stored on an external drive that I access via USB. I was thinking of moving the drive to plug it into the AEBS, and have iTunes access my music from there. I understand this will upset iTunes, since it wont recognize the HDD (since it used to be connected via USB). Is there a simple way to tell iTunes that the path of most of the music has moved to the network drive? Thanks a lot!
