Moltitudine translates to "multitude" or "crowd". It's a less common word than simply "gente" (people) and carries a slightly more formal or literary tone.
In the song, Grignani sings about being "Confuso nella moltitudine" (Confused in the multitude), highlighting a feeling of being lost and indistinguishable within a large, anonymous crowd. This word effectively conveys a sense of existential anonymity and the struggle to maintain individuality.
This song is a quiet confession about feeling worn down by time and unable to explain why. The singer tells a friend he can't go on the way he has been, even though he can't fully name what changed.
The title image, a man made of sand, captures that feeling: something solid slowly eroded by time and by the sameness of everyday life, until it finally gives way.
The chorus turns that erosion into a wheel that keeps turning, a reminder that everyone eventually faces this same wearing-down, whether or not they see it coming.
