In Brigitte Hamann's _Hitlers Wien_, a standard work on Hitler's Vienna
years, the author plays back a section of memoirs written at the direction
of the Nazi party by one of Hitler's friends.  Hitler is shown as having
been a Mahler partisan even at a time when Mahler had come under heavy
fire from anti-Semitic jingoists.  But he liked Mahler for the way he did
Wagner, not for his own works.  The Nazi-beholden book of course made sure
to add that the Fuehrer had been pro-Mahler despite his fundamental
distaste for "Israelites...  with bent noses"
