you're all missing the point, here. besides the whole issue of wanting to convey images and themes through words (which, last time i checked, most instruments can't use), there's also the issue that this is fucking donkey kong, for goodness sake. it's not like they made the appassionata sonata into a country song or something. just chill the fuck out and be happy that people (other than me, lol) care enough to put out a project like this.
if you're such a good music critic, write some of your own, asscan.
