The reason games are relatively safe from piracy is that a large amount of people play games on consoles, and I don't know many people who are willing to risk chipping a $400 console just for some copied games. Thus video games are still bought.
I'm sure if you could only play pirated music on a $400 iPod, not many people would risk breaking the iPod just to listen to a few free songs.
