I was going to mention St. Anger--it's like they did it on purpose, because occasionally there are bits that actually sound really good.

On the flip side, I often use Metallica's S&M for testing--it sounds really good! My favorite of theirs is the gold remaster of Master of Puppets--that sounds incredible!

I doubt anyone will ever look for it, but Gary Hoey's Bug Alley actually made me get into a car crash because it was mastered so badly! Tip--don't try and adjust the treble while driving. Not safe.

I am the Doctor, and THIS... is my SPOON!
