Query: A Masterpiece of Old-School Metal

I was very excited about this album when i first about it and OH MY GOD, it is an amazing album. I think this is something that Metallica fans should get because if they a planning to go back to old heavy anytime soon, this is a fresh start from megadeth. You guys did an awesome job making this! Dave Mustaine Rocks!!
