I also agree that the person's frame of mind, reference and mood play the major role outside of the music itself. I've been moved to watery eyes on a few occassions. This happens much, much, much more with movies which is why I enjoy cinema more than audio alone (cinema having more stimuli.) Many bash the home theater expierence but it by far trumps 2 channel audio for my enjoyment.
Now, to further add proof to my point, the last time I cried listening to music was listening to Mariah Carey's " Can't Let Go." Many would regard her as pop dribble but given the thoughts of my mother at the time I absolutey cried like a baby in my wife's arms and the song just helped release those emotions.
I remember the first time I heard Patricia Barber's " A Rush of Blood" from Cafe Blue (which again some may discard as not so avantgarde jazz dribble) on a Maggie 20 custom setup in a gents spacious family room. The sound ws so all encompassing that if not for two men standing behind me I may have watered up. I do remember purposely gathering my emotions...excitement and involvement. It was a wonderful match of song, system and room. The large room just melted away and had I been alone I may have been brought to tears, maybe. There is a certain physicality that a system can convey that can prompt an physiological and emotional response. Timbre, Tone and Bass response.
