Few weeks ago, I was in New York City and sitting at a Starbucks store. There was a music played and I had my iPod touch. So, I pulled out my iPod and sure enough, it was showing the information about the current music that was being played with a purchase option. So, what if we have similar options in most of the retail stores? How about in train or in airplane? How about in the city? This reminds me undersound, an interesting music sharing project conducted in London Tube with location-based service. This is also similar to Yahoo's Zurfer, a location-based photo sharing project based on geotagged photos on Flickr. Such integration of digital information and place will certain change the way we experience places and the way we relate to others.
