As Mike said in making of Meteora, we people only look at the results. Being a musician is stressful. Chester has a lot of points in expressing his soul out, hoping that his past memories will pass and disappear. He doesn't wish his past nightmares to haunt him.
Saying him or his band EMO is a crime to me. Just say 'Alternative Rock', 'Electronic Rock' or simply 'Rock'.
Okay, let's say, there are some people who like DBS and some people who hate DBS. So Chester makes the album for the people who LIKE. Those who hate is advised to avoid listening DBS and avoid insulting them. Chazy predicted this will happen. He understood his fans. He is a bit too selfish, that's all.
