Jimmy Fallon Declared Major Lazer’s ‘Lean On’ The Song Of The Summer

While our Song of the Summer voting is still ongoing, we might as well close up shop. Noted musical tastemaker Jimmy Fallon made a bold declaration for Major Lazer & DJ Snake’s “Lean On”:

Our musical guests tonight, they may have one of the hottest songs of the summer, maybe the song of the summer, tonight. Definitely already is.

Well, I guess that’s that. With that mystery solved, you may as well just watch a live performance of the song of the summer on The Tonight Show.
