Could Zing be the next killer app for music?

It's a music player; it's a social networking device; it's a tasty treat. It's Zing! Because all good products should onomatopoetic. A prototype of the innovative music player was making the rounds at the D4 conference today, and Wall Street Journal blogger Jason Anders covered the tech demo.

Broadly, Zing leans heavily on wireless connections to let users access music stored on a networked computer, or an Internet-based subscription service like Yahoo! Music, or even on a friend’s device that is within range — all through a seamless interface. Listening to a song on an Internet radio station and want to buy the CD? The iPod-sized Zing will (in theory) be able to sync up with an online music store to complete the purchase.
