creative people love their art, the rest of those fuckers just want to have a good time. the most innovative minds have always had a devotion to their work, from MLK Jr to Frank fucking Zappa. Its a mental mountain one must climb to do exactly what it is they want to and not sacrifice their representation for potential success. This is why the underground musicians in any genre are the outliers, weirdos, and typically far more unique individuals. They've promised themselves to make music based on what it is they have in their head and need to materialize. And this is why most famous musicians just add a semi-new spin on something already done.
