Accontentare means "to satisfy" or "to please," but in its reflexive form, accontentarsi, it means "to settle" or "to be content with what you have." It's a nuanced verb that goes beyond a simple translation.
In this song, the singer repeatedly tells the listener, "Però ti devi accontentare" (But you have to settle/be content). It conveys a humble acceptance of his limitations in writing the perfect song, inviting the listener to find beauty in its imperfections. This word captures a key theme of the song: finding contentment in simplicity.
Brunori Sas sets out to write his partner a special song, "una canzone per tirarti su" (a song to cheer you up), with a chorus that climbs while the tears come down. Then he admits right away: "Io non so fare davvero di più" (I really can't do more). It's a modest, very funny opening. If anyone calls it trite, he says, "facciamo finta che l'hai scritta tu" (let's pretend you wrote it).
The chorus is where it turns tender. He hands the song over: "prendila, cantala" (take it, sing it), play it on a rainy day when you're lying on the bed "a fissare le ore" (staring at the hours) or smoking away the afternoon. And if his words stop being enough, "buttale via e inventale tu" (throw them away and make them up yourself). The second verse jokes that he wanted a canzone popolare (a popular, old-fashioned song) with a chorus that "sa di Natale" (tastes of Christmas), and if it sounds like some old tune, well, tell everyone she wrote it.
Listen for the imperatives stacked with pronouns: prendila, cantala, falla, buttale, inventale. Each one glues the object (la, le) onto the verb, which is everyday Italian you'll hear constantly.
