Metallica's Trouble With Repetition

The only hope i have for one more great metallica record is if they can reunite with bob rock. If i were bob i would call him up right now and say guys let's do the black album again, we're not going to make the same record but we'll work on it as hard as we worked on the black album. Let me push you guys out of your comfort zone to write bigger songs that are more worthy of your power as a band. They've done far more top quality work than really any other heavy rock band including their idols like sabbath  they have earned the right to just make fun thrashy little songs they like.
