I'm trying to wrap my head around the absurdity of the question. If we're considering prog to be anything other than 4/4 or 6/8, in normal key signatures (that is, major and minor with no modal shifting), I'd probably have given up on music a long time ago.
However, if we're just talking prog bands like DT, Townsend, and Pain of Salvation, I'd probably still be obsessed with thrash/death metal (more than I already am).
