This interview is interesting. This is the problem that Bon Jovi is having since John Shanks has been in the band for so long.

During the making of 2003's "St. Anger", a petition that some 1,500 fans signed subsequently was posted online calling for METALLICA to dump Rock, claiming he had too much influence on the band's sound.

"The criticism was hurtful for my kids, who read it and don't understand the circumstances," Rock told Reuters. "Sometimes, even with a great coach, a team keeps losing. You have to get new blood in there."

Although St Anger was number 1 on billboard, Metallica need another producer because they knew that another album with Bob Rock would be on the same wheel and they had already been there too long.
