It’s a career first for Cazzu…

The 29-year-old Argentine rapper and singer and Santa Fe Klan have each scored their first No. 1 on Billboard’s Regional Mexican Airplay chart as “Tú y Tú,” with Los Ángeles Azules, rises 3-1 to lead the May 20-dated survey.

The new leader yields both Cazzu and Santa Fe Klan’s first champ in their maiden chart appearance.

“Tú y Tú,” released via SeiTrack/Disa/UMLE on March 10, takes over Regional Mexican Airplay in its eighth week after a 28% boost in audience impressions, to 8.5 million, earned in the U.S. during the May 5-11 tracking week, according to Luminate.

As “Tú y Tú” rises to the top of the ranking, Cazzu and Santa Fe Klan become the first artists to claim a No. 1 in their maiden chart performance among the nine tracks that have crowned Regional Mexican Airplay in 2023.

The last artist to pick up a first No. 1 in a first attempt was Mario Bautista, as “Brindo” with Banda El Recodo de Cruz Lizárraga led for one week on June 11, 2022.

Previously, Eden Muñoz completed the deed with “Chale!” (May 21, 2022).

“Tú y Tú” ascends 3-1 and sends Grupo Marca Registrada and Grupo Frontera’s “Di Que Sí” to No. 6 after its three-week domination, with a 39% dip in audience (to 5.2 million).

“Tú” also brings Los Ángeles Azules back to No. 1. The cumbia sonidera ensemble last ranked first through the three-week ruler “Nunca Es Suficiente,” with Natalia Lafourcade, in early 2019. In between, the group collected five top 10s, including the No. 2-peaking “Amor a Primera Vista,” with Belinda and Lao Ebratt, featuring Horacio Palencia, in August 2019.

Elsewhere, “Tú” continues its progress on the all-genre Latin Airplay chart, reaching its No. 5 high.
