I recently learned ...And Justice for All on guitar, and by god, it's a work of art. Starts out with a beautiful lick on clean and then gets really heavy. I love the guitars thrashing and answering each other throught the song. The vocals, punishing, James delivers, and they have haunting lyrics. Here are some.
Halls of justice painted green money talking
Power wolves beset your door hear them stalking
Soon you please their appetite, they devour
Hammer of justice crushes you overpower
To name a few. The chorus is absolutely fantastic. Riveting bass line, and unforgiving drum rolls, and crashing cymbals. Basically I'm trying to say that ...And Justice for All is Metallica's best song. Ever. Here is the link to listen to it, I think it's live, and not the original recording, but you should seriously check it out. Anyone agree, or think there are better songs?
