Anyway, my point was that one ought not to treat music like a drug, i.e. to deliberately seek something out to produce a specific effect. Of course music does effect certain emotions in one, but ultimately (and this was my point) my mood is more determined by the quality of the piece. I also think that music and musical works, if they are good, tend to be far more complex and nuanced than can be compartmentalised into crude and oversimple categories of emotion such as 'angry', 'powerful' (how can a piece be 'powerful' anyway?) etc.
