Best bands are prone to the word CHANGE because they are supposed to make music that doesn't sound the same. If a band continues to make the same music, then there won't be growth and development. And, slowly their music will not be amazing.
Also, a band didn't become a band because of the fans. They become a band because of their dreams. The fans are just supporters who supports them in their dreams not the ones who make their dreams.
That's ONE OK ROCK, isn't it?
