Is music a measure of my mental health

I'm not sure if there is a cause and effect relationship, but there definitely seems to be a correlation between how much music I get to listen to and how good I feel. Oddly, I've actually felt pretty good lately. I say, oddly because right now I've got enough stuff on my plate that I ought to be hiding under my desk rocking back and forth and gibbering about the squirrels that seem to be haunting my dreams. I'm not. I've had several opportunities lately where I had a chance to spend several hours listening to music. Not good music mind you, just music. Who knows, it might just be all of the solvent fumes I've been breathing lately.
