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.
My advice to people today is as follows: if you take the game of life seriously if you take your nervous system seriously if you take your sense organs seriously if you take the energy process seriously you must turn on tune in and drop out.
