I have 2 computers, both with iTunes music on them. I am going to buy an iPod. How can I get the music off of both computers onto my iPod? The guy at Best Buy told me you have to register the iPod to one computer and I won’t be able to download from both computers. Unless I get the music from one on a cd, I don’t know how to do that, he said something about “data” on the cd?? There are over 500 songs, so without having to use 25 or more blank cd’s to download my music, is there a short cut? If you reply, please speak in easy to understand terms, I don’t know a whole lot about computers, so I have to know exactly how to do it step by step. Thanks!!!!!
