To answer the original question, no, and no. I used to like Metallica a lot, but my musical tastes have matured since then.
Now I primarily listen to Iced Earth, Nevermore, Testament, Megadeth, Symphony X, Tourniquet, Deliverance, and Flotsam & Jetsam. I'm going to try some Blind Guardian stuff next.

Every board has it's "Metallisheep", just ignore them. They'll get over their obsession eventually.
