Find it

I don't have a satelitte radio but I kinda want one. Here's a cool feature I would want to exist should I ever own one:

I tell the radio the song I want to hear, and it tells me if it's playing anywhere. It's probably a shot in the dark, but this would be a REALLY fun game to play with friends. You could take turns and whoever finds a song first wins. Or make up some other rules. In practical terms, it may not work out unless you're looking for really popular songs. I know that sometimes I want to hear a song on the regular radio and find it magically as I scroll through stations...so I guess anything is possible.
