I do think sometimes there's danger in guest appearance mania. I've seen too many examples that sound cool on paper like 'Oh get that guy to sing the hook on that guy's song ' and then that's all it is. It's a cool idea that sounds good on paper.
I discovered early on that some performers live their life in order to act so all their relationships are simply an experience that they can feed back into their work. Which I find vampiric.
