I think Metallica has sadly been pretty irrelevant for quite a few years now, and a cheesy title like "St. Anger" sort of goes to back this up. I'm not trying to spit in the face of anyone's favorite band, but I think their time has passed. Not a very quanitfiable statement, perhaps, but it's what I've thought about them for years and years. Only the most hardcore fans still defend them, it seems.
Oh, and the fact that Metallica is touring with the likes of Literally Limp Bizkit and Linkin Log Park just goes to prove my point even more. LB has had a few hits, but doesn't anyone else get tired of the teen-angst-I-hate-my-parents-and-blame-them-for-everything rant? Heck, even Fred Durst said last year that he realized all the hate-filled lyrics he was writing were immature. And Linkin Park is very catchy but weak. Down with Nu-Metal! Down with Nickelback! Down with the sickness! ;-)
Oh, and Creed really, really sucks. Just saying.
