Simone & Simaria wrote the song with Rafinha RSQ and Kayky Ventura.

Simone wanted to record the song immediately, but Simaria had another idea in mind, coming to reveal the name of Anitta to share the vocals.

The music video for the song was released on January 6, 2017, directed by Anselmo Troncoso and features Peter Hermann.

Troncoso's script follows Simone & Simaria and Anitta in a setting with lights and fire.

"Loka" was the most watched Brazilian music video on the Vevo platform in 2017 and also the most-viewed female Brazilian music video and the 10th most-viewed female music video in 2017, in addition to being the most popular clip featuring a Brazilian female lead in YouTube history, with more than half a billion views, and the second overall (in November 2017) behind only the song "Bum Bum Tam Tam" by MC Fioti.
