Luis Mexia is celebrating a career first…

The Mexican singer-songwriter has earned his first No. 1 on a Billboard chart.

Mexia leads the Regional Mexican Airplay chart dated October 22 with his first collaboration with Grupo Firme: “Calidad” rises to No. 1 after two weeks in the runner-up slot.

“Calidad,” released via Music VIP on July 12, reigns in its ninth week on the ranking after it added 14% more in audience impressions, to 7 million, earned in the U.S. in the week ending Oct. 16, according to Luminate.

It just took a bold move from Mexia to achieve the feat: a fan of Grupo Firme, Mexia used social media to announce his interest in recording a duet with the group’s lead singer Eduin Caz. He also plotted with his followers to support the idea. After the Tijuana-based group’s social media was bombarded with requests, Caz agreed, and a music video of the song followed.

The new champ earns Grupo Firme its sixth leader. The group has achieved a steady run of chart-toppers since its first No. 1 in June 2020 (through its featured role on Lenin Ramirez’s “Yo Ya No Vuelvo Contigo”).

Mexia, meanwhile, scores his first champ on any Billboard chart. Notably, only one other entry precedes “Calidad” in his chart career: “El De Los 20 ‘El Cachorra’,” with Enigma Norteño, which reached No. 33 on Regional Mexican Airplay in December 2021.

Beyond its Regional Mexican Airplay coronation, “Calidad” climbs 11-6 for a new peak on the all-genre Latin Airplay chart. It’s a fifth top 10 for Grupo Firme, while Mexia secures his first in his first try.
