Engavetarlo' comes from the word "gaveta," which means "drawer." The verb "engavetar" literally means "to put something in a drawer," but in a metaphorical sense, it means "to shelve something," "to put it aside," or "to bury it."
In the context of the song, Eladio Carrion uses it to criticize record labels that sign young artists and then "engavetarlos" – essentially, they sign them but then don't release their music or promote them, effectively burying their careers. It's an interesting and critical look at the music industry.
Eladio Carrión spends "Cuenta a 10" talking himself down before he says something he'll regret. He opens with the flex: "Grammy nominado, voy pa' dos, Manuel Medrano" [Grammy nominated, going for two, Manuel Medrano], then thanks John Leguizamo by name for a blessing he never explains. The hook keeps pulling him back to one line: "Respira y cuenta a diez" [Breathe, and count to ten].
He's mostly annoyed at the industry, not at people. Labels chasing whatever works on TikTok, songs that live or die on a dance trend, executives who flip on you once you've made them money: "Pa' después virarles las tortillas, como un omelet" [to later flip the tables on you, like an omelet]. His answer isn't to fight it, it's to ask for patience: "Rezo a Dios pa' que la paciencia dé" [I pray to God to grant me patience]. He admits he's changed too: "Yo no soy quien era, no me hagas volver" [I'm not who I used to be, don't make me go back], which reads less like a threat and more like a reminder to himself not to slide backward.
