Narcos: Mexico - Season 1, Episode 3: Soundtracks

Rafa, Chapo, and the rest of the boys are partying at an upscale disco dance club when Rafa spots a girl making eye contact with him from upstairs. The music continues for the duration of the scene.

A campesino hits play on a jukebox. Kiki sits down with one of the workers and offers him a cigarette.

Kiki follows a group of field workers into a dive bar. Once inside, he looks for the right guy who might be able to give him some information about where they work.

Samba jazz song that the band plays at the beginning of the hotel scene

Song starting after the beef at the wedding

At the wedding

Kiki gets off the bus to work in the marijuana field.

First song as the narrator talks about the innovation of Miguel Angel.

This Samba plays in the background of the party while Felix and Don Neto are talking. What was played was a cover of the classic song Mas Que Nada. Although it's not exact, Jessy J's version of it is the closest I've found. I hope this helps!
