M'appiccec is a Neapolitan dialect word meaning "I argue" or "I fight." It's a more colloquial and emotionally charged term than the standard Italian litigo.
In the song, the singer uses it to express the frequent arguments he has with his loved one, highlighting the passion and conflict in their relationship. This word offers a glimpse into the rich regional variations of the Italian language.
"Non È Vero Che Sto Bene" is Sal Da Vinci's confession that a breakup left him anything but fine, even though pride keeps making him say otherwise.
He picks up his phone to call her, then writes a message and deletes it before sending. Pride is the real enemy here: it's what started the fighting in the first place, and it's what stops him from admitting how much he misses her.
By the chorus he drops the act. He wants her back, he's ready to do things her way this time, and he's asking her to forgive him one more time. He pictures showing up with a red rose, waiting for her at home, brushing her hand.
The song closes under the stars with a promise: they won't fight like that again. It's a simple, heartfelt plea to undo a breakup neither of them really wanted.
