"This is America" first rap song to win song of the year

Childish Gambino's "This Is America" has won the Grammy for song of the year, becoming the first rap song to win the prestigious award.

Gambino reportedly declined an invitation to perform at the Grammys, and he also wasn't in the house to pick up the prize.

The Grammy for song of the year honors song writers, unlike record of the year, which goes to the artist.

"This Is America" beat out "Shallow," "The Middle" and other big hits.

Presenters John Mayer and Alicia Keys accepted the award for the absent rapper.

The song caused a stir last May when Gambino released its ambitious video, which was full of racial symbolism and violent imagery.
