This song is a dramatic plea to a "Radio Rompecorazones" [Heartbreak Radio] to stop playing sad love songs. The singer is clearly going through a tough breakup and doesn't want to be reminded of past loves or the pain he's feeling. He's begging the radio, "ya no cantes por favor radio rompecorazones" [please don't sing anymore, heartbreak radio], because he wants to believe that true love still exists, even if his current situation makes him doubt it.
He's convinced that he was the one who "dañó su corazón" [damaged her heart], and he doesn't want the radio to rub it in. He just wants to dream that she'll come back to him, and he's ready to sing about "el verde del amor" [the green of love] instead of heartbreak. It's a really relatable feeling when you just want to escape the sadness and believe in a happy ending, even when everything around you is telling you otherwise!
