Why wasnt dave mustaine inducted in the rock and roll hall of fame with metallica?

Cause Dave hasnt had anything to do with Metallica since Kill'em All.|||Good question. I never thought about that. He probably has too much pride. Although I doubt they offered.|||because dave mustaine actually only played on the four horsemen and maybe one or two others on kill 'em all.|||for the same reason bob rock wasnt either|||Who cares the rock and roll hall of fame is a HUGE JOKE! They have rappers in the "rock and roll" hall of fame. Plus metal isn't supposed to be mainstream, so I hope Dave is happy.
