Well if it's purchased and you have an iPod just plug it into your new computer, and transfer purchases and authorize your computer...

If it's not.

If it's not purchased:

Plug it into your new computer Then

My Computer %26gt; Click the iPod %26gt; Then Folder Options %26gt; Show Hidden Files %26gt; Go into the hidden folder %26gt; Copy the music into the Music folder on the computer... don't worry about the weird names once you add them to iTunes they will go back to there original name.How do I shift music from my iTouch to my iTunes library?
