YouTube video about how to transfer music from iPod to iTunes:
Many friends asked me, “My computer crashed, and I lost my music in iTunes library, how do I restore my iTunes library? Can I restore it from my iPod?”
The answer is “Yes!”.
Though iTunes can only copy one way: from computer sync to your iPod, so we must use some other software.
All you need is a third party program: iPod to Computer Transfer, just download and install Windows Version or Mac Version, then you can restore your iTunes library from your iPod Mini, iPod Shuffle, iPod Nano, iPod Classic, iPod Video, iPod Touch, iPad, iPhone, iPhone 3G and iPhone 4, include all videos, photos, books and songs with playlist, play count, artwork and more.
It very easy to use, just a few clicks.
