This is REALLY cool.
Take your iPhone and hold it up to a speaker/radio/etc playing nearly any song and run Erica Sudun’s insane new app, Listen. It will ‘sample’ whatever is near the iPhone’s microphone and after a couple of seconds will display the song, artist and album of whatever it heard. I’ve had about 75% success with it so far.
This isn’t necessarily new technology as I recall hearing about services that could do this before, but this is a new free app for your iPhone (sorry Touch users – no microphone on you!).
It’s not on installer yet so you’ll have to ftp it to your iPhone for now
It’s available on Installer – thx Conner!
