I have already imported my songs from limewire into itunes, and now I want new songs off Limewire but I don't want them to get mixed up with songs I already have on itunes. If I delete songs from my Limewire library, will the songs I have already imported and put on my ipod stop working, or are they permanently in iTunes until I delete them out of there? Thanks for answers, apologies if this question has already been answered
