It’s a special first for Eden Muñoz…

The Mexican singer-songrwiter and producer has reached a new career milestone as “Chale!” rises 2-1 on Billboard’s Regional Mexican Airplay chart dated May 21.

It’s his first No. 1 on the chart — and chart entry — as a solo artist, after fronting Calibre 50 for all 21 of their No. 1s from 2013-21. He departed the group in January.

“This is my first No. 1 as a soloist but not the first in my career,” Muñoz tells Billboard. “It is something that fills me with satisfaction and gives me the drive to continue working for the better, to keep evolving, remain in the public’s favor, which I believe is the most important thing in this beautiful career.”

It’s the first champ for Muñoz after he parted ways as the lead singer of Sinaloan norteño band Calibre 50.

The group’s 21 leaders, all with Muñoz, are the most in the chart’s history (it launched in 1994). Banda MS is in second place with 17 No. 1 hits.

“Chale!” gives Muñoz a first win in his first chart appearance as a solo act. He’s already logged a second chart entry, as his featured role on Banda MS’s “Hay Que Hacer Dinero” rises 38-28 in its second week on the chart.

“Chale!” takes the Greatest Gainer honor of the week thanks to 23% increase, to 7.74 million audience impressions in the week ending May 15, according to Luminate.

“The song’s musical production addresses as such a fresh and innovative concept, a style that results from the mixture of instruments representing the classic big band (slide trombones, trumpet, sax, drums), with a fusion of current norteño, in search of a new aspect of the Mexican Regional, without leaving aside its essence,” adds Muñoz.

As a soloist, Muñoz joins three other acts who have clocked their first No. 1 on Regional Mexican Airplay in 2022.

Here’s the new leaderboard:

Banda Rancho Viejo de Julio Aramaburú, “Me Vale Perderte” April 16
Maluma, “Cada Quién,” with Grupo Firme, Feb. 5
Virlan García, “Híbrido,” May 14
Eden Muñoz, “Chale!”, May 21

Beyond its Regional Mexican Airplay coronation, “Chale!” enters the top 10 on the all-Latin genre Latin Airplay chart with an 11-4 jump in its seventh week. It’s also Muñoz’s first top 10 there.

“The adoption of the tuba and Toloche al norteño has undoubtedly come to complement ‘Chale!,’” Muñoz concludes. “It gives it the characteristic touch that makes it, without a doubt, a natural and unmistakable success that can be enjoyed at any time and in any situation.”
