Again, please keep in mind that this is not a review, just an "answer" to the complaints this 2 CD set has recieved.
This is NOT a greatest hits collection and was never intended to be. According to the liner notes, the entire band picked out their personal favorites spanning their Columbia/CBS years from "Sin After Sin" through "Painkiller". And, Metal Works is the finest JP Columbia/CBS collection that exists - until it's replaced by a remastered version.
Yes, there are favorites missing; that's what the studio albums are far. Sure, buying "Sin After Sin", "Point Of Entry", "Turbo", "Ram It Down" and "Painkiller" (the five weakest Halford-era, Columbia/CBS releases) sounds like a waste of money, but how else can you get classics like "Starbreaker", "Diamonds & Rust", "Don't Go", "Hot Rockin'", etc.? ...not to mention "The Green Manalishi", "Love Bites", "White Heat, Red Hot", "The Sentinel" "Better By You, Better Than Me", "Running Wild", "Some Heads Are Gonna Roll", "Grinder", etc., etc., etc.
Hell, I purchased all of their remastered discs, made several CD-R mixes, which included the tracks above, and turned around and sold them here on Amazon.com. Sure you lose a chunk of change in the end, but isn't getting your favorite Halford/Priest tracks most important?
