POLL: WHO WAS/IS THE MOST IMPORTANT MEMBER OF METALLICA, PAST AND PRESENT?

The question is simple enough but the answer sure ain’t easy. Who was or is the most important member of Metallica, past and present? Take all things into consideration — musical ability, songwriting, charisma, performance, motivation, and intangibles, aka the “X” factor. For the sake of keeping things realistic, I’ve left out original bass player Ron McGovney, but I can’t imagine any of you would’ve voted for him anyway; and if you’re that one dude who would have, congratulations, you’re a douchebag.
