La Maquinaria Norteña is back on top…

The Mexican quintet’s “Eres Ese Algo” rises 3-1 to lead Billboard’s Regional Mexican Airplay chart dated February 25.

“Eres Ese Algo” reaches the summit just six months after La Maquinaria Norteña claimed its first radio No. 1 during its 10-year-plus charting career on the Regional Mexican Airplay chart, which launched with the No. 40 debut and peak of “Ayer y Hoy” in 2011.

Before “Eres Ese Algo,” “50 y Cincuenta” earned the norteño ensemble its maiden champ on any airplay chart last August. In between the band scored a No. 38 high through “Mejor Ni Me La Nombren,” with Neto Bernal (Aug. 27).

“Eres Ese Algo” shoots to No. 1 on Regional Mexican Airplay in its 14th week on the chart.

It takes the lead boosted by 28% gain in audience impressions, to 10 million, earned in the U.S. in the week ending February 16, according to Luminate. The increase secures the track the Greatest Gainer honors of the week.

The song is the second single of Al Derecho y Al Reverso, the seven-track set released on October 14 via Azteca/Fonovisa/UMLE, which reached No. 10 high on Regional Mexican Albums on the January 21-dated ranking.

In addition to bringing La Maquinaria its second airplay No. 1, “Eres Ese Algo” also secures the Azteca label its third ruler on Regional Mexican Airplay, among its 72 chart entries spanning 12 years. Prior to “50 y Cincuenta” and “Eres Ese Algo” by La Maquinaria, Azteca scored its first leader, also last August, through La Fiera de Ojinaga’s “Luna de Miel.”

Beyond its Regional Mexican Airplay coronation, “Eres Ese Algo” ascends the all-genre Latin Airplay list, rallying 10-4, besting La Maquinaria Norteña’s previous peak of No. 9 with “50 y Cincuenta.”

“Eres” was written by Keith Nieto, founding member of the Chihuahua-based band.
