Ha*Ash is a very popular pop duo in Mexico, though they were actually born in Louisiana. Sisters Hanna and Ashley spent their childhood living half a year in Mexico City and the other half in Lake Charles, Louisiana due to their father's job, and since they signed with Sony Music in 2002, they've earned popularity among the public due to their vocal talent and catchy tunes.
To this day, they're one of the rare cases of pop acts that actually have some sort of relevance on digital platforms, in an era where urban and regional music (banda) are the most dominant genres.
Their 2014 video Lo Aprendí de Ti from their live acoustic set Primera Fila - Hecho Realidad, has just reached the 1 billion views on their YouTube channel.
Personally, I think they have better songs, but hey, at least is better than the other stuff that has become more popular in the past few years
I particularly like this better
but nothing beats the classics
And I'm just learning they performed with Maluma too
