How do I authorize songs in my iTunes library?

How do you transfer iPod songs to your library that thinks it already exists on iTunes?

• My iTunes library is all wrong. It won't display my iPod songs on my laptop. So, in order to listen to my iPod songs, I have to plug my iPod in, and listen to my iPod's library. But once I disconnect the USB cord, the library goes back to the stupid original songs that I don't want. It's very confusing, and it's frustrating me. I try to drag the iPod songs into the existing iTunes library [You know, like when you're creating a playlist] and it won't let me. On my mom's computer though, iTunes cooperates and uploads and updates songs normally. But she had to wipe her hard drive clean because of a virus, so the songs don't exist anymore. PLEASE help me. This is very frustrating. I hope you understand it well enough to help me. Thanks.

  You could use the free program called Sharepod to put the music from your iPod back onto the computer. You can download it from http://www.sturm.net.nz/website.php?Section=iPod+Programs&Page=SharePod
