I totally agree with the sentiment of Alex Ross from his book "The Rest is Noise" that segregating music into Music and Classical Music is WRONG... (a disclaimer, that is one of just two books I had read about music in my entire life! The other one was about Pink Floyd, the band Alex Ross referred to as "sounding like Mahler"). Most of us (myself included!) take this distinction a bit too serious...
Once this segregation is disregarded as moot, I will be thrilled to hear DSOTM in surround with Gilmour guitar flying around me as much as "classical" recording from the perspective of being inside the orchestra. Totally agree with the guys that this has nothing to do with the original "intent" of the composer, but listening to Tchaikovsky under late Celibidache no one can pretend that they are listening to the "original intent" of the composer!... Beautiful, transcendent, but Definitely not the original intent!!!
