Ever stuck trying to name a song you heard? Now the computer will do it for you. “You call a toll-free number on your cell phone and play the music you’re trying to identify for 15 seconds. The program then contacts you via text message, whether it can make the ID or not. Sorry, but humming a tune won’t work. But the service can distinguish between different performers’ versions of the same tune to match audio “fingerprints” from its database of more than 2.5 million popular recordings. The database doesn’t include classical music or jazz.”
