There is really no way to be nice about this so I will just come right out and say you truly are an idiot.
Either that or you are very ignorant and have not even listened to any metallica in a very long time.
Beyond Magnetic? They did not have one single fast in your face music on there at all. It was pretty much Alt. Rock
LuLu?

I won't even comment on that one.
Death Magnetic? Maybe a couple of fast songs but nothing near as intense as this latest song. Mostly Rockish The Unforgiven type songs.
St. Anger was a joke. Weird, gay vocals and lots of soft rock/experimental type shit. Some kind of Monster

ooh scary. Lame as shit.
Then there is LOAD and Reload which made Metallica seem like a waste of a good LOAD themselves.
If you are into OLD Metallica than yes, this new song seems to be the best release in decades. Nothing else they have released since And Justice resembles old Metallica whatsoever. I am open to corrections but I have listen to them all and you obviously have not.
Not to mention get your fucking genres right. Punk Rock? GTFO
