It enabled me to Easily and quickly backup my songs, videos, photos, playlists, podcasts and more from my iPod to my computer and iTunes. Now I can sync smoothly again.

connect the ipod to the computer from the usb port. all the songs will synchronize automatically.

yes,you can make it and all you need is a three party utility which I recommend Aniosoft ibackup. It enables you to transfer iPod's music and other content to any storage device and iTunes as well. And both the backup in the storage device can be convered and restored with no any change and no any risk.And the data in the iTunes is quite in accord with the iPod's data including its playlists,rating and etc. So in your case,you can make a music transfer from your iPod Nano to iTunes with this tool and make a backup for the ipod's content in your computer as well. There is a note that needs your attention,you have to turn off the auto sync of the newly installed iTunes before you can make this transfer.
for your convenience,I'll add the links here:
