There were experiments that zipped music pieces, I think, and then classified the compressed files by similarity. They got rather interesting resuls. But I do not remember much details. It was, I believe, about 20 years ago.
That sounds like a really cool project, I will def give it a look.
I still think this has much more to do with the structure of language than the abstract conception I have of intelligence, and I would be interested in having conversation w/ someone for whom the opposite is true.
Asked Google: "Clustering by compression".
