Name that tune

I am the worst when it comes to music and remembering who sang the song or what the title of it may be. Having said that, I LOVE MUSIC! I often will want to purchase some random CD... and have gone so far as to sing the song I'm looking for to the clerk (much to their chagrin), wishing I had somehow captured the song when I initially heard it.

I have now found a solution.

Genius...
