I know of a piece of software for use on OS X 10.4+ called Senuti
that allows users to download songs from their iPod into iTunes. It works well and I like it a lot.
My mother needs a piece of software that performs a similar function for her Windows XP machine. Obviously, you can't just pull songs from the iPod onto the hard drive (even with disk access enabled).
Anybody know of anything like this that works with XP?
