Some babies like to hear lullabies like "Twinkle Twinkle" when they're upset.
Not this little girl! Looks like her music tastes are a bit more mature than that...
That's "Copy Of A" by Nine Inch Nails! According to her dad, this is the only song that puts her in a good mood when she's upset! He said, "I thank Trent Reznor [lead singer for Nine Inch Nails] for turning my crying child into a smiling dancer."
