I have my iTunes library on a very old computer and I don't have it on my new one. B/c of space issues, I won't be transferring it (it lives on Google Play but Bose refuses to support that). I'd like to be able to access this library but don't want to have to leave this computer on. Is there a way to either sync this library so I don't have to have the computer on or somehow put it on my external drive? I have an external drive on my Airport Router but haven't been able to access it via NAT for whatever reason. Is this possible?
