Podjacking - To Know Me, Know My iPod

An intriguing piece in today's New York Times:
... people whose iPods are filled with opera and people whose iPods are filled with rap would have very different tastes in jewelry. 'The concept of bling-bling is going to be very different for these groups'.

Hmmm... digitized bits of Pavarotti and of Chingy live happily side-by-side on my Treo 600. Can knowledge of this help someone deduce that I'm totally not into bling-bling ?!
