good to see you around David
You're right about all of the above, but interpretation of music is somewhat tricky. If something sounds like rock music, does it make it rock music? With your explanations, no, it doesn't.
...with the case of Shenzhou, it's a manipulation of a recording, is it not?
...and I was having this similar discussion with someone else recently. Sort of like O'Rourke's 'Eureka' album. his music spans multiple genres, but since 'Eureka' doesn't sound much like an electronic album, does it make him an electronic musician?
