Who do you think you are?

This is my new favorite song. I love female singers. I heard this on the radio a month or so ago and rushed home to google the lyrics I remembered- but had no luck. I thought it was Adele-like, but knew it wasn't her.  Then Glee happened. I knew I had found the song- and I guess all of America found it at the same time too. Happy weekend. Turn up the music and sing along.
