Query: Once upon a time

Once upon a time there was a band that rocked!! called Metallica. Please, lets get serious, and lets get honest, this album is the worst thing that Metallica has done. Doesn't matter how many times you hear it, music is not about getting used to or just because you hear it so much that you actually start to like it. Music flows through your ears and gets into your soul, but this just go through my body straigth to the toilet. Please if you are a big Metallica fan, don't buy this album, you'll be terribly dissapointed. Better to keep your memories of Black, Justice for all, or Master of Puppets.
