The application Listen, developed by Erica Sadun is nothing new amongst cell phone users of other brands and service providers, but for iPhone users on AT&T, it’s a brand new sight. Listen takes a sample of a song and then looks for it in a song database. Listen then provides a Song Title, Artist, and Album name. Listen lets you search for the song on iTunes or email the information. All listen requires is that you hold the iPhone to the speaker and wait until it’s done recording the 5 second sample.

The application works very well most of the time, but only likes mainstream music. If you try weird genres, it’s most likely not going to come up with a song. You also don’t need to be directly near a speaker. I tested it tonight inside a wrestling gym and as long as the music over powers background noise, you will get a result. Listen can be downloaded from Installer.app.
