Going more for the music vs. "other" distinction, Mike Hawley's (1993) MIT PhD Thesis, "Structure out of Sound" used measurements of the length of constant-frequency peaks in the spectrum for discrimination. Steve Smoliar and I extended this work in Lonce Wyse and Steven W. Smoliar, ``Toward Content-Based Audio Indexing and Retrieval and a New Speaker Discrimination Technique''. (to appear in) D.F. Rosenthal & H.G. Okuno (eds.) Readings In Computational Auditory Scene Analysis. (Lawrence Erlbaum, Mahwah NJ) 1998. (linked from my homepage) Of course, using only information in the signal, there can be no perfect discrimination between music and other since the domain of music in general (e.g. electro-acoustic music) is all sound. - lonce
