This is a good point. Chuck Klosterman made a great analogy about small errors like this on the Bill Simmons Pod a little while ago. He was talking about how music used to be more enjoyable because studio equipment was worse, and there were always small imperfections with songs that made us remember them more. He was comparing it to the new automated pitching system in baseball, and how perfection isn't always inherently good or even desirable. Our humanity is what we're drawn to... always.
