hi,all. I have two computers with iTunes. All the music from Computer 1 has been downloaded to my iPod. I would like to download all that music onto Computer 2. However, Computer 2 has newer music on it that is not on my iPod/Computer 1. I can't figure out how to get the music from my iPod onto Computer 2 without erasing the new music. Suggestions? Thanks. PS: Both of computers are on Mac OS.
