Okay! So I love this band. They are known for doing covers of artists songs. And they are incredible. I have at least 4 of their songs on my ipod. And some of their versions, I think are better than the original. Fun fact the girls singing this song, also sand the song for the new Macy's commercial. ENJOY!
