I just finished Narcos last night. They did a really good job with Escobar's character, I honestly liked him at first. As far as music goes, I'm pretty much in the same boat as JorickThis is the theme song from Narcos. It's "Tuyo" by Rodrigo Armarante. They have it on Google play music, and I kid you not, I've played it at least 100 times. Mostly because I'll listen to it 10-15 times straight at a time.
If you haven't watched Narcos yet, do so now.
