A misguided study?

H. Jennings, P. Ivanov, A. Martins, P. da Silva, and G. Viswanathan, “Variance fluctuations in nonstationary time series: a comparative study of music genres,” Physica A: Statistical and Theoretical Physics, vol. 336, pp. 585-594, May 2004.

In classic physics style, this work essentially reduces the music signal to be an amplitude envelope, and then claims truths on entire genres based on correlations.
