49. Tove Lo - Cool Girl

On the surface, Tove Lo's new hit "Cool Girl" boasts a snappy, earworm chorus and an empowering message of self-reliance. Beneath its chill exterior, though, Lo's song burns with a passion bordering on rage, and sinister sonic undertones suggest an unreliable narrator who doesn't always mean what she says. The more layers one pulls back from this song, the more Lo's source material—the novel and film "Gone Girl"—comes to the fore, turning "Cool Girl" into the kind of pop smash that sticks in your head in more ways than one. Featuring:Tove Lo - Cool GirlDaft Punk - Harder, Better, FasterAlessia Cara - Scars To Your Beautiful
