bogey -
I put those shows (Aida, Wicked, Rent...) into the Big Broadway Musical category - big sets, big orchestras, lots of belting in the vocals. I like them every once in a while but you have to vary the diet (as Sondheim would say) with the off-Broadway stuff (BARE) and the less mainstream stuff (Assasins) and the new stuff (Avenue Q's puppets are an interesting twist).
I sing for myself. I sing when I want, whenever I want to, just for me. I sing for my own pleasure. Do you understand that?
