Balorda is a fantastic Italian adjective that translates to "foolish," "clumsy," or "awkward." It's not a word you hear every day, which makes it a special find.
In the song, Olly uses it in the key phrase "balorda nostalgia" (foolish nostalgia). This perfectly captures the feeling of a nagging, silly longing for the past that trips you up in the present. It describes a nostalgia that is unwelcome and almost clumsy, making it a uniquely poetic and memorable expression.
This song is all about that feeling Olly calls "Balorda nostalgia" [Stupid nostalgia]. It's a look back at a relationship that's over, but he's clearly not over it. He's stuck in this loop of hoping tonight might be the night they get back together, even though a neighbor smoking on her balcony tells him it probably won't be.
He misses the simple, everyday things. He wishes he could go back to a time when all they needed was to "Ridere, piangere, fare l'amore" [Laugh, cry, make love] and then fall asleep on the sofa. He can't shake the little habits of their life together, like setting an extra plate for dinner or looking for her when his back itches. He's blunt about how lost he feels, telling her directly: "'Sta vita non è vita senza te" [This life is not life without you].
