What's your favourite band?

This is a neat tool which in time could turn into something really special. It uses Google Talk to monitor what you're listening to on your computer and then uploads the data to a listening chart. Havent seen much activity on it since I last looked, but this technology mashed up with MSN Messenger or Apple Talk and you'd have something to shout about. Given how the downloads chart is now taking over the mainstream charts, some kind of "listens" count could supercede the "radio plays" count.
