Music Database Software For An IPod, Is There A Software Program That Allows It To LOAD Music On Another Computer?

For an iPod, is there a software program that allows it to LOAD music on another computer? - music database software

I'm happy about computers to change and I have a database of great music that I do not want to lose. The easiest way to transfer that burden would be my music on iPod to another computer, but I know he removed iPod, if there is nothing (or similar non-music) on iTunes, the other computer. I know it's a program that I can delete downloading music not just from the computers of other people without fear of me, but I can load my music on another computer. Where can I find? What's your name?

And if you use certain programs cool little iPod to another team, I would be happy to recommend this course too.
