I am a big Metallica fan. I have all their albums and have seen them in concert. The only album I did not like was St. Anger. Wow, that was awful. I almost drove off the road the first time I listened to the CD in the car.
So I pre-ordered Death Magnetic (their 9th album) with some apprehension. It arrived last week...
First Impression: Not great, but not St. Angers either.
Over time: Now that I have had it in my playlist and heard some songs a few more times, it is starting to grow on me.
I would try and judge this album on its own, and not compared to Master of Puppets. Metallica can never go back to the old days, because... they are old. I wish it was possible to recapture the fire of youth. You know what song I really liked? The Tuesday's Gone cover on Garage Days. Despite the name, it doesn't all have to be metal for Metallica.
