There is no definition but "awesome!" they've sold fuck loads of albums, they still fuckin rock the stage live (ST ANGER tour ruled) and still produce good music to the day! (i'd like to clarify that i do like Megadeth aswell, there is no need for the bickering considering megadeth have released fuckin loads anyway!) James Hetfield is God! Kirk is Brilliant, Rob is Fuckin Raw! Lars is short! hahaha that little dane fuckin rules too! "Metal God" bless you Dave Mustaine aswell for releasin more metal (it means more CD's you little moanin bastards!)
Battery, One , Creeping Death, Dyers Eve, Fade to Black, Nothing Else Matters, Seek and Destroy, Master of Puppets, Sanitarium, Disposable Heroes! it goes on i might aswell list the whole list but u don't wanna read all of it you'd rather listen to Metallica!
