I just bought this album, and I have to say I am not a huge fan of it, but that has not stopped me from playing it all the way through.
I like new Metallica better than the old Metallica (YES, YOU READ THAT RIGHT) just because the band's music in today's times is much closer to my favorite genre of hard rock, and that alone has enough appeal for me to continue to listen to it. I for one, am very happy that Metallica has gone mainstream, because their music now resembles a fusion of rock-borderline-alternative and metal which is just awesome!
"Ain't my B****" is absolutely FANTASTIC and I cannot stop listening to it, but the rest of the album pales in comparison to it, which is disappointing considering that's the first track. I still like this album just because of the new direction Metallica goes with these songs.
Regardless of my somewhat negative feelings about this album, nothing will ever stop me in my quest to listen to all that is Metallica.
