I have all of my actual music files on an external hard drive, which is connected to my time capsule, so its wireless. I set the iTunes preferences so it wouldnt copy the actual files when i moved them into the library, just refrence them. It works fine to reference and plays fine, but when i shut down my Mac, the next time i open itunes, all of my music cannot be found. i can double click on a single songs, wait for the drive to spin, and it will play that song, and stop, because all the others cannot be found. is there a way to have them always located, while still on the wireless external?
