Meaning of "No One Knows" by CocoRosie

The lyrics of "No One Knows" by CocoRosie evoke a sense of mystery and solitude. The imagery of a train cutting through a mountain and traveling through the moonlit night conveys a feeling of isolation and obscurity. The train's whistle serves as a haunting soundtrack to this journey, enhancing the sense of loneliness and secrecy surrounding the protagonist's destination. This can be interpreted as a metaphor for a personal journey or inner exploration that the individual undertakes alone, away from the prying eyes of the world. The secrecy and ambiguity of where the train is headed suggest a sense of independence and autonomy, with the protagonist choosing to venture into the unknown without the interference or judgment of others.
