I really don't know, I always liked music and have been singing (by myself, like when I listen to music) my whole life, I've stuttered since I was 4-5 years old. There's also alot of famous muscicians that stutter, we have one here in Sweden called "Orup" and he was in the jury of X Factor, he stuttered a few times every show. He never stutters when he sings and I know a few stuttering people who doesn't stutter when they sing also. I thought it was the same for everyone! Edit: Fuck I just watched the video, how can they say: "You should just sing all the time!"?! I would get furious, fucking pricks.
