I'm with Spaw! Music makes me feel good!

It could be that the positive physical effects of music enhance the powers of the brain... relaxation and all that. But with all such hypotheses and theories, what works for Jane may not work for Sue. So you have Jane saying, wow, I tried this and It Really Works! And Sue's over in the corner going, what a bunch of Hogflap.....

That being said, however, I firmly believe in the power of music.
