This was released as a promotional single from Fifth Harmony's debut EP, Better Together, reaching #104 on the Bubbling Under Hot 100.
Fifth Harmony's Lauren said during a performance on Live From MTV that each track on the EP "has a different kind of vibe to it." She added the overall concept is being yourself and OK with what you're feeling," "So if you're having a good day and want to go out with your girl and see a guy or whatever, 'Don't Wanna Dance Alone' and 'Me & My Girls,'" Lauren continued. "And then if you're having one of those days where you're in a relationship and it's hard, we have 'Who Are You.' So it's a teenage-girl little diary."
