I think all kinds of anime songs will sound very sad (you don't have to have lyrics, you can also have a single).

There is a kind of music in the world called sadness, which plays slowly with the melody. It's like being at the end of heaven and being exiled to the edge of hell.

Suddenly, heaven and hell are so close!
