...has anyone else heard of Shazam? It's this app for (I know WP7 for certain-there are probably other platforms as well) Winows Phone 7 that will recognize -and pretty darn accurately too- any song you can play to it. Some of the limitations are that it does have to "hear" the song-you can't just hum the melody. But, I found it fairly useful for songs that I liked on the radio. Just curious.
