yeah, lamarca, thanks for spelling out your thoughts on this clearly, and I see what you're saying but I actually do nearly all of those things you mentioned on a pretty regular basis! To be honest, I do not quite understand what you mean by some of these things. I mean, "learning songs just to show how clever you are" means what, exactly?

Changing keys? You mean, within a song? or transposing it from the usually key into one that is comfortable in your range?

Not sure what a melodramatic dynamic shift is; but I always thought shifts in dynamics were considered important in singing. Melodrama is probably to be avoided at all costs but then again I would bet different people have different definitions of that!
