As I stated a while back, its all some big conspiracy.
Dave has been doing the solo's for all the Metallica albums since day one, and Kirk does the leads on all the Megadeth albums. The only album Kirk was allowed to do leads on was the black album (video proof) and St, Anger (again, video proof). This is all some big publicity stunt.
Anthrax only hired Bush for "x" amount of time to gear up to get Joey back, it was all a plan.
Overkill and Testament hold 90% of all stock in Microsoft.
Max didnt leave Sepultura, he records every album, they forget to put his name on the credits.
Black Sabbath and Motorhead get royalties from EVERYONE in metal because they wrote every single goddamn good riff there ever was.
Slayer really attend Catholic church every saturday for mass, and are on Gods payroll.
And last but not least, GN'R never went away, they all record songs on the weekends, and Axl is going to run for California Senate, Republican.
