What are song good Clical pieces for mage?

I wouldn't use anything that is too famous. Now don't get me wrong...I LOVE the music that has been suggested...but I'm not sure that it would be the best choice, only because some of it may be distracting (due the complexity of clical music)...people may tend to want to listen to it!...instead of just relaxing....I guess you could experiment though or give people choices as to what they would want to listen to (I don't know if that's appropriate etiquette at a mage place, is it? i have no clue) But anyway...at many spas I know they usually play a lot of New-age type of music - often something has a japanese/other asian feel and something that would be more simple or hypnotic. Like I said...clical might be too melodious and complex....but maybe that's just me! I know I would tend to listen to it rather than totally submit to relaxation! :P
