My kids each have their own Apple Ipod. They also both have their own computer with Itunes loaded on each one. Is there someway for them to download songs from each other's Itunes library? It looks like you can only download songs from one library and not both. It's as if the Ipod is machine specific to only 1 Itunes library at a time. Has anybody run across this? If I download from Itunes Library on the A computer but then try to download songs from the B computer it wants to erase everything that was downloaded from the A computer first before it will let you add songs from the B computer.
