Well put, all three of you. Moya's music is personal, and she does not try to 'preach' anything through it. She just let it speak for her and itself.
I personally believe that music is intrinsically spiritual. I think it was Jimi Hendrix that realised this when he said, "Atmospheres are going to come through music, because music is in a spiritual thing of its own..... "
Music can both lift you up and make you feel sad. It can make you excited, or it can make you feel angry. For example, how many times have you been walking along the road and a car comes zooming by very aggressively, and you can hear this loud, thump-thum-thump aggressive music coming out of it? Very rarely does an aggressive driver get caught listening to Beethoven!
