Why do you people insist on constantly selecting one member of the band and giving them all the credit? They've all contributed to the band and it's about time you realize that. Envying someone for whatever characteristic appeal to you is one thing, but don't do it that way. Josh didn't do anything by himself therefore it's kind of wrong to put it that way. The music changed becuase they didn't want to make the same old music again, it had nothing to do with them being happy or no
