I'm getting a refurbished ipod on Thursday and I found out that I'm going to loose some of my music because it is not saved on my itunes.

Does anyone know of a free program that is able to rip music from your iPod and put it onto your iTunes?

I found a few programs but I'm not sure if they are safe I was hoping that someone here might be able to help me.

Thanks for your help and I apologize if this is in the wrong forum.
