Comete means "comets" in Italian. It's a celestial and somewhat rare word to find in everyday song lyrics, making it intriguing.
In the song, GionnyScandal uses it poetically to describe a perfect union: "Finché saremo due stelle comete, complete, come te" (Until we are two comets, complete, like you). It evokes an image of two individuals shining brightly together, completing each other like a pair of celestial bodies.
"Come(te)" plays on a pun: "come te" means "like you," and the title also spells out "comets." GionnyScandal builds the whole song around that double meaning, comparing the person he loves to a comet streaking across the sky.
The verses are full of small, clumsy, tender moments: wanting to give a hug but his arm has fallen asleep under the pillow, asking to be told when he messes up, promising never to let her get hurt. It stays light and playful rather than heavy or dramatic.
The chorus is where the pun lands: he calls himself her other half, her gravitational center, and imagines the two of them as comet stars, complete only when they are together. It is a sweet, uncomplicated love song about wanting to be someone's missing piece.
