Farfalle literally means "butterflies" and is the title of this massive hit song.
While we have a similar idiom in English ("butterflies in your stomach"), sangiovanni puts a unique spin on it. He first sings "Non volano farfalle" (Butterflies don't fly) to say his love isn't just a simple crush, but then creates a new poetic image: "Volano farfalle sulle lampadine" (Butterflies fly on the lightbulbs), comparing his attraction to an irresistible pull towards a bright light.
This song is all about a love that feels different from the usual clichés. Sangiovanni starts by describing a really sweet, domestic scene: his girlfriend's small house has become their house, and she's covered the fridge with photos of them together. He jokes, "C'è la mia faccia / E mi fa ridere / Che sono da tutte le parti" (My face is there / and it makes me laugh / that I'm everywhere). It's a cute, specific detail that makes the relationship feel real. He says that even after seeing the world, the best place to be is in her arms.
But then comes the twist in the chorus. He sings, "Non volano farfalle" (Butterflies don't fly). This is a play on the Italian phrase for being in love, which is to have butterflies in your stomach. He's saying he doesn't feel that fluttery, nervous excitement. Instead, he feels like he's lost his emotions and asks her, "me le ritrovi tu?" (can you find them for me?). He describes her as a breath of fresh air, "una boccata d'aria," someone who helps him breathe when life feels toxic. The song suggests a deeper, more calming kind of love that brings him back to life, not one that just gives him a temporary rush.
