Let me start out by saying the Metallica HAS EVERY RIGHT to play whatever kind of music they want to. That being said, let me also say that I have every right not to like it. Everyone is entitled to their own tastes and opinions, and I simply do not like this album. It's not about them changing their style, it's about the end product, and I don't care much for this music.
On another note, music can bring back memories for me: I can hear a certain song and instantly recall a time and place in my past -- maybe you're the same way. A lot of music brings back good memories for me, but this brings back some bad ones: the hot summer of 1996, living in a crummy apartment with my girlfriend (now wife), and the engine in my beautiful 1984 Firebird on its last legs.
Just one more thing: does anyone else find it ironic that a band that supposedly hates being labeled chose to name themselves METALlica?
If you're looking for some good Metallica, I recommend "Master Of Puppets" or "Ride The Lightning".
