Doesn't sound too impressive to me (Score 1)

I really didn't read through the article, but I'm surprised he doesn't cite this well-known article:

@article{ li92random,
author = "Li",
title = "Random Texts Exhibit Zipf's Law-Like Word Frequency Distribution",
journal = "IEEETIT: IEEE Transactions on Information Theory",
volume = "38",
year = "1992",
url = "citeseer.ist.psu.edu/li92random.html" }

In fact, many (possibly quite random) phenomena in nature exhibit a Zipf's law-like distribution. I think it would come as more of a surprise to me if music did not.
