People get so preachy about the superiority of original music lol. Problem is, 99% of original music sucks and will never be heard by more than a few friends, family members, and the poor bartender that can't wait for you to be done. The other 1% of songs written that "make it" include the one hit wonders and mindless garbage that we all generally turn our noses up at... yes, even that stuff is better than the other 99% of (horribly) written original music. So yes, of course The Beatles/Black Keys/Ray Lamontagne/etc are better than a cover band. But a cover band that can play covers well is better than some pretentious group of losers talking about their "artistic integrity".
P.S. If you don't like this post, then you simply don't get my art and thus you are the problem, not me. See how stupid that sounds?!!!
