Just in case waiting for a train in the London Underground while listening to your iPod has already become passé, a group of techie art types are putting together a new musical installation in the Tube network based on Bluetooth, which they call "Undersound." From the group's site: "In the same way that Londoners leave and retrieve newspapers as a kind of common good, so too will they with music. Unlike newspapers though, which are of unknown origin, each track in Undersound will have a birth-place, giving added meaning." The idea for Undersound is that people can transfer songs via Bluetooth (using public domain, non-copyrighted, royalty-free or creative commons-friendly music, of course) to a "transfer point" at a particular station. Then others can come along with their own mobile phones and pick up some new tunes as well, leaving a trail of metadata behind them, begging to be analyzed -- in a good way. We hope. We're not sure if there's going to be a huge difference from the tracks dropped off at Waterloo Station versus the ones at King's Cross, but we'll find out once the researchers get their gear up and running.
Update (Oct. 24): We just got an email from Peter MacLennan, a spokesperson for the Transport for London office saying: "We have no plans to introduce this service on the Tube and have not received any approach from the organisation who are indicating that this will be reality."
