We just arrived in Austin, there are so many hashtags and emphatic statements filling our twitter timelines already. Whether you'll be in Texas or elsewhere this week, keep on top of the conversations with The Pepsi Music Index. We picked 250 emerging bands and Pepsi got a bunch of MIT brainiacs to build a discovery engine that ranks them in real-time according to your tweets, status updates and blog posts. How does it work? Something about a "proprietary algorithm" that we don't understand. Who'll come out of this festival-week with the best shot at success? Check out the Index throughout the week, see who's getting talked about most and know who's next before your friends.
