Who Uses Rear Surround Speakers For Music Playback?

My take on it is that it’s all good...whatever the listener prefers.  There’s this “as the artist intended” school of thought.  I prefer the “as the listener intends” school.  Sometimes this listener likes “as the artist intended” so I have a fairly minimalist (although I did break down and buy a Loki...lol), 2 ch rig sharing my Audio cabinet aside a 5.2 setup for when I want a little more “stadium” than the artist intended....

doesn't work for me......I have a 5.1 system in another room....whenever I want to hear music I go to my 2 channel system.

Whatever sounds good is where it’s at. Those who thumb their noses at it can stick the whole fist up there.  
ML Motion 2s sound pretty sweet in back.  Best with seperate amps.

When I am in the family room listening to music I will sometimes run the surround system with the rear speakers on and it sounds fine to me. I have a Velvet Underground CD box set of their album Loaded and it includes an Audio DVD in surround and it sounds pretty cool. 

With that said serious listening is always on the 2-channel system.

If the music was recorded with surround channels I'm inlined to use them, but I tend to avoid the derived surround modes the Bryston SP3 processor can generate.  I use KEF LS50s for side and rear surround.
