This is getting amusing now. Why arent they free to make the music they want? Why is it such a bad thing to, after proving themselves as a "heavy metal" band, try other avenues of creativity? It is just as much as "selling out" to be comercially accessable, as it is to NOT in fear of losing your fan base (IE PANTERA). WHo cares who taught who how to play metal? The act is they still made killer albums to the metal community, then in 1990 in the "rock" community. Who followed whom? Check your album timeline, Megadeth's "changes" damn near coincide with Metallica up until Youthanasia when Dave realized that chasing Metallica was a fools game. Case in point, lame or not, Metallica was a defining band up until about 1990. Then they because a "business" per se.
