Adorno's reputation as a musicologist has been in steady decline since his death. His sweeping criticisms of jazz and championing of the Second Viennese School in opposition to Stravinsky have caused him to fall out of favour. The distinguished American scholar Richard Taruskin declared Adorno to be "preposterously over-rated." The eminent pianist and critic Charles Rosen saw Adorno's book "The Philosophy of New Music" as "largely a fraudulent presentation, a work of polemic that pretends to be an objective study." Even a fellow Marxist such as the historian and jazz critic Eric Hobsbawm saw Adorno's writings as containing "some of the stupidest pages ever written about jazz". The British philosopher Roger Scruton saw Adorno as producing "reams of turgid nonsense devoted to showing that the American people are just as alienated as Marxism requires them to be, and that their cheerful life-affirming music is a 'fetishized' commodity, expressive of their deep spiritual enslavement to the capitalist machine." Irritation with Adorno's tunnel vision started even while he was alive. He may have championed Schoenberg, but the composer notably failed to return the compliment: "I have never been able to bear the fellow [...] It is disgusting, by the way, how he treats Stravinsky."
