Corrompere means "to corrupt" or "to bribe." It's a strong and intriguing verb that isn't commonly found in everyday song lyrics, making it stand out.
In the song, the lyric "Abbiamo provato a corrompere il sole per allungare le notti insieme" (We tried to corrupt the sun to lengthen our nights together) uses the word metaphorically. It paints a vivid picture of the lovers' intense desire to extend their time, even attempting to "bribe" or "corrupt" the natural order of the sun to make the nights last longer. This poetic and slightly rebellious usage makes it a memorable and enticing word.
"In Città" is Marco Mengoni's ode to losing yourself in a city night with someone you're drawn to. The singer is searching for something missing from everyday life, ready to reach for the sun even if it means getting burned, and finds that release in the anonymity of dancing with someone whose heartbeat isn't quite his own.
Milan becomes the backdrop for this restless connection. Streetlights, smoke and sirens blend into one night where nothing else matters except being together, even if it doesn't last. By the end he's still searching through the city's glow, unsure where she's gone but unable to stop looking.
