Hi, I am looking for a way to stream my 300GB itunes music collection externally so that I can listen to music while at work. The music is on my MBP, but I would rather find a solution that does not require me to keep my MBP on all day. I think I need some kind of network drive : the music would be backed up on it (wirelessly and seamlessly through TimeMachine if possible) and would stream from it, either to my iPhone with an app (?) or to my office computer's iTunes. I'm not sure if it helps, but i already have an AirPort express. Any ideas? Thanks in advance for your help.
