I was just thinking of the book "Renderman Companion", and how in many ways this problem of vinyl noise simulation is analogous to image-shaders. One thing I've noticed is that although Pixar's approach is often procedural/algorithmic they have for a very long time relied on artists to draw things like dirt maps, and dust-and-scratches texture maps to layer into their shaders.
It might be that you need loops on top of something procedural to get something really organic sounding. In other words, a combination of both approaches.
