Si Supieras by Mexican rock band PXNDX is a confessional love anthem packed with nervous energy and self-deprecating charm. Throughout the song, the singer repeats the phrase “si supieras” — “if you only knew” — as he imagines revealing everything he hides: how deliciously sweet life feels when he thinks of the other person, how he secretly believes they are “the sky,” and how desperately he longs to be close. Every line drips with the awkward honesty of a shy admirer who thinks he is “siempre aburrido” (always boring) yet dreams of winning the listener’s heart.
At its core, the track captures the insecurity that flares up at the start of a crush. The narrator lists his quirks (“como arroz con leche”), admits he feels unworthy, and pleads, “ayúdame a cambiar” — “help me change.” The repetition of these confessions mirrors the loop of anxious thoughts in his head, making the song instantly relatable. Si Supieras turns vulnerability into a catchy rock plea, reminding us that even the most timid hearts can roar when love is on the line.
