Shazam on iPhone could change music discovery
Shazam has been around for a few years now--CNET U.K. took note of the service back in 2006--but with today's launch of Apple's App Store, it could become a whole lot more popular. It has the potential to change how people discover and buy music.

"for example, once you have a shazam account, if you're at a club and you want to know what song is playing: dial 2580 and hold up your phone towards the music being played (with the free shazam application already installed on your phone). shazam then checks against it's library of 5 million tracks. if it finds a match, it sends a text to your phone with the information. if on the off chance, it doesn't find a match, there's no charge." -fluxlife
