How well-known is this website? →[More:]I used it to answer an AskMe question and was re-flabbergasted by its awesomeness. It's such a great magic trick: hear a song you don't recognize, dial the number, hold your cell phone up to the speakers playing the song in question, and a few seconds later, the service texts you with the artist and song information. WahwahWEEwah! I've tried it five or six times with some moderately obscure stuff, and can't remember it ever crapping out.

I was surprised to see that it hadn't been FPP'd before, but is that because everyone's already familiar with it? Also, could an FPP about it be considered Pepsi Blue, seeing as how it's a pay (albeit cheap) service after your first ID?
