To me, the producer is there to make sure the album gets done and gets done as good as possible. So if that means that you have to help write a bridge or help write a part, that's what you do. If that means you help tune the guitars, then that's what you do. If that means all you do is tell the band their takes are good and they should stop f——— with things, then that's what you do. If it means you don't do anything except make sure the band doesn't fight, then that's what you do. Sometimes it's a little more stressful than others, but for the most part, you just don't complain about it and you just get it done.
