Demencia translates literally to "dementia" or "insanity". It's a powerful, dramatic word that immediately grabs your attention.
In the song, Junior H sings, "Finjo demencia pa' no saber" (I feign insanity so I don't know). He uses this striking metaphor to describe pretending not to realize his partner's lies, choosing willful ignorance as a way to cope with the heartbreak. It's a unique and poignant way to express the complex emotions of denial in a broken relationship.
Junior H serves up a raw confession in “DEMENCIA,” where he acts like he’s lost his memory to dodge an avalanche of lies. The narrator is torn between cold skepticism and lingering hope, asking the million-peso question: “Did you ever really love me?” He recalls begging for explanations that never came, so now he flips the script and refuses to give any of his own.
The chorus claims the world is bursting with pleasures and new women—his supposed escape route from heartbreak. Yet every boastful line is undercut by the truth: he still can’t shake his ex, no matter how many parties pile up. The song blends swagger with sorrow, painting a picture of someone who masks pain with bravado, only to admit in the end that forgetting is harder than he advertised.
Junior H taught himself guitar and accordion off YouTube while working the kitchen at a Wendy's in Utah, where his family had moved in 2015 from Cerano, Guanajuato. Born Antonio Herrera Pérez in 2001, he uploaded his own songs under the name until one of them, "No Eh Cambiado", passed two million views and convinced him to make a career of it. The debut album Mi Vida en un Cigarro arrived in 2019.
He writes sad music, mostly: heartbreak over sierreño guitars, the corner of corridos tumbados people call urban sierreño. $ad Boyz 4 Life II (2023) reached number 14 on the Billboard 200 carrying no guest features at all, and produced "Y Lloro" and "Las Noches". Away from his own records he sings on "El Azul" with Peso Pluma, and on "Lady Gaga" with Peso Pluma and Gabito Ballesteros, which entered Hot Latin Songs at number one. In February 2026 he and songwriter Gael Valenzuela released the joint album DEPR</3$$ED MFKZ, a number one on Billboard's Top Regional Mexican Albums chart.
