Ruby's New Favorite Song

I happened to have Pandora on today and this song happened to come on.  Ruby was in the room and the next thing I know we are looking on YouTube to see if we can find it again, and again, and again, and again ...  You get the idea.  We have listened to it so many times at this point that Ruby is in fact starting to get the words and singing with it and I just heard her in the bedroom singing it to herself.  What can I say? The girl has got good taste!
