The Mexican songwriter Peso Pluma’s album “Génesis,” which came out on Thursday, has a good chance of selling a lot of copies. Tens of millions of people have already streamed its advance singles. Peso Pluma’s other songs released this year have received hundreds of millions of plays, including “Ella Baila Sola” (“She Dances Alone”), a collaboration with Eslabon Armado. 4 on the Hot 100, Billboard’s mainstream pop chart.

Peso Pluma is 24-year-old Hassan Emilio Kabande Laija, whose stage name means “Featherweight.” In songs called “corridos tumbados,” or “trap corridos,” he is at the forefront of young Mexican and Mexican American musicians who are modernizing classic sounds for a wider audience.

He’s not on his own.

There are subtle distinctions between styles and song forms in Mexico.)

In contrast to nearly all of the other best-selling pop of the 2020s, regional Mexican music is a folky, natural alternative. It uses mostly hand-played, acoustic instruments instead of computers: brasses, accordions, guitars, and reeds Waltzes actually make up a lot of the biggest hits, like “Ella Baila Sola.”
