yea, sometimes i think the lack of perfection helps you focus on the bigger ideas. like how making 2d plots with the xkcd style kind of tells your brain to ignore little noise in the line. same with tuning and tempo and whatnot- not every not is perfect, so your ear ignores the little imperfections. of course, if there is too much imperfection, signal to noise ratio gets out of whack. but i think this is part of the reason lots of music has drones, melocially, or texturally (think indian classica, jazz cymbal or brushes, etc) ...it kind of thresholds alot of non-musical noise.
