If I was passing by, will I stopped and listened?

Most likely not. I am not good at distinguishing good or bad musician. And I probably will think it was just noises. That's right, to enjoy music you need to like the music that was playing. Complicated music made people sick or bored. I don't like to pretend I know music and I believe most of the people are like this. I also hated the article mentioned the musician's ticket price. For me, even it was free I wouldn't want to listen to it. The experiment is totally bogus.
