This song "Black Envelope" is really unique and fascinating. The melody is haunting and has a certain kind of mysterious charm that makes people feel like they are in a hazy and enigmatic world. The lyrics are profound and thought-provoking, seeming to hide many secrets and stories. It's a song that can really arouse people's curiosity and exploration desire in the digital age. However, some might say that it's a bit too dark and moody, not everyone's cup of tea. But that's also what makes it stand out and have its own unique style.
