I have an older nano with hundreds of songs that I downloaded from Limewire a few years ago. I would like to download these songs to I tunes and then transfer to my new nano. I am afraid that if I connect the old nano to my computer it will flush all of the old songs from the nano and transfer my current I tunes songs. Bottom line- I don't want to lose these songs. Is there any way I can download these songs into I tunes?
