A company with origins in the Bay Area and operations in the UK, Shazam, will identify and tag a song using your mobile. Hold your mobile to the sound source -- a jukebox in the bar, speakers at the mall -- and the phone gets an SMS with the song info. It also updates a home page with a link to purchase the CD.

The FAQ explains that you can tag any song playing over speakers -- not live! -- in the U.K.(orange, 02, tmobile, vodaphone) or Germany (vodaphone only), and that the sercice will expand to other countries.-- but Shahid pointed out that the service is not available in the U.S., for licensing reasons.

And it doesn't work with humming. Yet.
