An interesting book review, Joe_F, though it didn't really explain to me why you want less of it. The more that's out there, the bigger the choice. It might take more effort to sort the wheat from the chaff but it should be possible to find something that suits.

The first thing it shows, for me, is how subjective the appreciation of music can be. The reviewer sets out his own stall by the comment:

"Briefly, in my book popular music peaked about 1900 and became vile about 1940."

but, for me, the period between the two world wars was the Golden Age. Others, of course, will have their own views.
