A lot of music doesn't do one thing or another. It just doesn't do anything. Then there are those pieces of music that thrill your soul. It's such a wide range, and it's really interesting that we all love different things.
Any new ideas go into PiL. My inspiration is everything that the human being gets up to. I don't listen to any music when I'm in PiL-zone, because influences can poison your well. Otherwise, I listen to anything.
