Metallica's most recent mistake...

Recently, Metallica filed a lawsuit against Canadian indie band Unfaith for using the cords E and F in a way that causes "confusion, deception and mistake in the minds of the public." Metallica wants this band to stop using these cords or pay them 50% of the revenue generated from the songs. I think this is ridiculous, but it's a proper follow-up for a band that I feel has been on the wrong side of many issues over the last few years. Starting with the Napster suit, through the recent decision not to feature music on iTunes, and now, to this. I think Metallica only cares about Metallica and that in the end will hurt them.
