Played By: David Guetta, Avicii, Dogblood, Major Lazer, Chuckie

Whether it was pop superstar entertainer David Guetta on the mainstage, Skrillex and Alvin Risk dropping it in their B2B set at last Friday's private party at the Red Bull Guest House, or Major Lazer or Chuckie performing on Ultra Music Festival side stages in between, the Plastik Funk & Tujamo house tune "WHO" was heard everywhere. A certified party-starter, this one really has no frills to it. Instead, the track has a relatively simple chord progression characterized by a horn lead and jungle-esque chants (as in the vibe, not the style of music) accenting the pounding beat. The single is the first of a few Plastik Funk & Tujamo collabs and we're actively awaiting the next ones! If you had told me I would have heard this song more in Miami than Zedd's "Clarity," I would have told you that you were insane. But here we are in the aftermath of Miami Music Week and the historic two weekends of the Ultra Music Festival, and "WHO" was the soundtrack of the 10 days.
