That. Some of us LIKE things like that. I like happy things as well, but songs that are sad and so emotional like a lot of SW's songs just really connect with me. He's said in a couple of interviews that he isn't an overly negative person, he just knows that a lot of people, like himself, find beauty in sadness.
If SW started writing happy songs, I would still listen to him and love every thing he does, but I think it would be a lot harder for me to connect to his music.
