I'm not sure I understand what you're asking.
If you're asking whether you can play the music off your iPod on her computer then the answer is yes. Simply plug the iPod into the computer and it will autodetect it and launch iTunes in response. The iPod will register as a library in iTunes and you can play any song it it like any other.
If you're asking whether songs can be extracted from the iPod the official answer it no. Apple doesn't want you to extract songs from the iPod and iTunes' inability to do this is evidence of that.
However, luckily there is software, out there, that will allow you to do exactly this. In fact, they sit unencrypted on your iPod so you can do this yourself with no extra software other than the file browser on your OS. However, they have been renamed so the only way for you to know which song is what file is to listen to them (or compare their exact file size). If you have a large library, this can be too tedious to be realistic. Luckily,
PodPlayer can extract the music files while creating a reasonable file name from the iTunes tag information. Even if this isn't want you were asking for, you'll probably still find this useful. Personally, I keep a copy of this program on the iPod myself, so it's always there when I need it...
