my girlfriend would like to take songs from lime wire and put on her apple ipod

As per the rules here at D-A-L:

4. Discussing P2P file sharing programs such as Kazza and Imesh is fine, however PLEASE DO NOT ask for any assistance in using, finding or sharing files using P2P programs. As many of you are aware, these programs can be used to share copyrighted material which is illegal.

Asking your question to Google often brings results.

As soon as you finish downloading, it should atomatically go into your itunes libary, but if that doesn't happen, open limewire, then go to your libary, highlight the song that you want, then left click and drag over to itunes, and hover the mouse over MUSIC, it should say COPY, if it does, let go of the left click and they should copy into your itunes libary.
