With soundtrckr, users can create and share their own stations instantly, seeding playlists from a database of music that covers tastes ranging from the most mainstream to the most obscure. For instance: a Washington, DC user can create a station of 80s Russian pop hits that have been out of print since Bill Clinton was president. She tweets a link to her station and a friend in San Francisco decides to tune in; using soundtrckr, her friend can listen along in real time, song for song. Word spreads from there, and as more people tune into the station, each listener can determine the others' locations, converse through an integrated TCP/IP chat feature, and share the station with their own friends via Facebook, Twitter, or email.
