The Songs of Summer 2013

UBIQUITY  This L.A. crew’s flabbergastingly catchy track was huge in California last summer, and it’s become something like the twerking national anthem.

SOCIAL POWER  For a week or two in late July, it seemed like every video on Vine was a “Thun Thun” joke.

CONTROVERSY  “Thun thun” is yet another nickname for ecstasy.
