need to know the name of a song, but don't know who sings it or anything else?
when you hear it, call 866-411-SONG, hold your cell phone up to the speaker...and wait for your SMS message with the title/artist.
i tried it twice with Psycho Killer from the Talking Heads and Cowboy Song from Thin Lizzy and it worked both times.
of course, my cell phone is now strewn across the dialers of the world i'm sure, but still...pretty cool.
