I think we use music, subconsciously perhaps, in a restorative way, like a little self medication for the mind.
When all the world seems to have gone crazy or the nutters seems to have gotten the upper hand, or when I feel disillusioned or dispirited perhaps even with myself, I find Bach more than anything else restores my mind back to balance.
