Had trouble deciding between this and the acoustic version. I heard the original first then the acoustic version on the Comedy Bang Bang Podcast: https://www.youtube.com/watch?v=LZLq9m3BQro 2
My husband and I were kind of obsessed with this song the whole time I was pregnant. We listened to it enough that our baby immediately chills out when we play or sing it because she recognizes it from her time in the womb.
