When a genre has been around as long -- and stayed as relevant -- as the corrido in Mexican music, you're probably going to want to listen to what it has to say. This is particularly true with the corrido, which is, by definition, a song that tells stories. The corrido has been a part of the musical culture of Mexico (and, to a lesser degree, other parts of Latin America) for centuries. It served as a news outlet long before modern media existed, providing people with news of current events, battles fought, heroes and villains, and other important information. Corridos were then passed from singer to singer so that the songs also became a living historical archive. Today, the corrido is primarily a source of massive hits: This centuries-old genre regularly climbs the pop and regional charts. But in the modern form of the narcocorrido, it also still serves its original purpose: providing news and documenting the history of the (often violent) cross-border drug trade -- sometimes so accurately that "narco" singers are targeted by drug cartels. We covered as much of this long, fascinating and sometimes downright torrid history as we could in this playlist of favorite corridos, new and old.
