Regarding Gun'n'Roses, I'd be embarrassed to mention more than 5 songs of them I really like :/
Well I do like Metallica but they have Lars and Kirk... two of the world's most overrated musicians.
Metallica sold over 50 million copies of the laughably bad "black" album, but only about 6 million of the genre defining Master of Puppets.
People are stupid.
IMO, the "black" album is masterpiece of recording / mixing / mastering.
