Proceso literally means "process". But in this song, the phrase "la del proceso" is a modern, colloquial way of describing a serious, long-term partner.
It refers to the person you were 'in the process' of building a life with—your ride-or-die, the one who was with you through thick and thin. The singer deeply regrets leaving "la del proceso" for someone superficial, making this a unique and heartfelt term for a meaningful relationship.
This song is a massive lesson in regret! Grupo Frontera and Manuel Turizo tell the story of a guy who made a huge mistake. He left a wonderful, genuine partner for someone flashy and materialistic, and now he's kicking himself for it. He puts it so bluntly: "Cambié una interesante por una interesada" (I changed an interesting one for a gold digger). It's a classic story of choosing style over substance, and he pays the price.
The lyrics are full of great comparisons that show just how badly he messed up. He says he "Cambié oro por plata" (changed gold for silver) and that his ex was his whole universe, while the new girl was just a star he crashed into. The most important idea is in the title itself: "No se deja la del proceso" (You don't leave the one who was with you through the process). He's talking about the person who was there for him through the hard times, before the success. While the new girl wanted "Louis Vuitton," his old love "sin nada me quería" (loved me with nothing). It's a painful realization that the best thing he had is now gone because he fell for someone who was only in love with his "posición" (position).
Grupo Frontera were playing weddings and parties around Edinburg, Texas, deep in the Rio Grande Valley, when a TikTok clip of their cover of Morat's "No Se Va" got away from them in 2022. The five of them are Adelaido "Payo" Solís III on lead vocals, Juan Javier Cantú on accordion, Alberto "Beto" Acosta on bajo quinto, Julian Peña Jr. on congas and Carlos Guerrero on drums. What they play is norteño sitting on a cumbia backbeat: miserable lyrics at a tempo you can dance to.
"Bebe Dame" with Fuerza Regida took them to No. 1 on Hot Latin Songs, and "un x100to" with Bad Bunny went to No. 5 on the Hot 100 and won the 2023 Latin Grammy for Best Regional Mexican Song. Their debut album El Comienzo won Best Norteño Album the year after, followed by Jugando a Que No Pasa Nada in 2024 and Lo Que Me Falta Por Llorar in 2025. Shakira called them in for "(Entre Paréntesis)", Maluma for "Por Qué Será" and Carín León for "Que Vuelvas". In 2026 they took two Grammy nominations for Best Música Mexicana Album.
