Yeah metallica's changed their music by tunning down and suff like that but there trying to fit in and make music for the kids today to listen to. You cant just say they lost it, Kirk can still break necks with his solos, and james can throw down a super fast rythm. Now new musicians today are throwing in solos, and if thats what everybody wants then thats what Metallica will give. My point is over 20 years and still rocking out your gonna change thats the way it is. There still kick ass!
