You can't do opera when already from the 10th row you can only see little dolls on the stage. In such an enormous space you can't put much faith in the personal presence of the individual singer which is reflected in facial expressions among other things.
I think people appreciate a songwriter who shows different sides. The whole angst thing is cool but if that's all you've got it's just boring. Everything I write whether it's happy or sad has a sense of humor to it.
