Dicha translates to 'joy' or 'bliss', but it's a more profound and poetic word than the common alegría.
It suggests a deep, fated happiness, like a true blessing. In the song, Marco Antonio Solís sings "...por tanta dicha que me das" (...for so much bliss that you give me), using this beautiful word to express an overwhelming joy that enriches his soul.
Mexican singer Marco Antonio Solís doesn't waste any time beating around the bush here. He kicks things off by admitting he cannot hold back what is in his heart anymore: "Quiero decirte esta noche sin vacilación que ya no aguanto" ("I want to tell you tonight without hesitation that I can't take it anymore"). The whole track is a bold confession to someone he's stuck in the friend zone with. He sees this person everywhere he looks, comparing them to an optical trick with "En todos lados te apareces como ilusión en mi mirar" ("Everywhere you appear like an illusion in my sight"), while swearing their eyes bring light to his whole life.
The real punchline comes in the chorus, where Solís drops the nice-guy act and spells out his exact goal: "Yo quiero ser más que tu amigo" ("I want to be more than your friend"). He tells her that not even the moon can shine brighter than she does tonight ("en esta noche no hay más luna que, como tú, me alumbre más"), claiming that having her around makes his soul feel rich with happiness. It is straightforward, incredibly catchy Latin pop about putting your heart on the line and taking the ultimate romantic gamble.
