Hrmmm....
To slam Metallica on their efforts for mainstream attention is faulty in this discussion. Megadeth tried just as hard. The difference is that they were not as successful. (IE - cartoon shows, WCW theme songs, Ozzfest, bringing Nu Metal bands on the road, changing their logo to a "softer" logo for RISK after Met did it for LOAD, etc, etc).
Also, let's get serious, LOAD and RE-LOAD both are a HELL of a lot more solid than RISK or WORLD NEEDS A HERO.
If you prefer Megadeth's songs overall, that's one thing. I don't think the purpose of the thread was to bring up credibility, because Megadeth is just as guilty. Not Metallica's fault that they were more successful.
