Step 1: Get the Software, Plug It In, Copy
Go to www.cnet.com and in the downloads tab, type in Ephpod. There is only one result, so click on it. This program, as far as I know, only works with Windows. Download the program and fire it up. It will ask you to plug in your iPod and select it from a source list. Once the data base is loaded, find the songs that you want to copy and click them. You need to hold down Ctrl to select songs (or shift) but don't hold it while you scroll, otherwise it will zoom in and out. Once you have the music selected, press Ctrl+Alt+C to copy. A dialog window will come up, telling you to tell it where to put the copied music. I like to put it into the iTunes folder. Once it is copied, go into that folder and just drag and drop it into iTunes.
