Okay, I can understand the hate for Metallica today, but their older stuff should keep them out of the generic category.
Dio, Journey, and Dokken shouldn't be in that category anyways.
Yes, they definitly should. Pre-Black Metallica is the only thing on that list that is not generic.
Dio, Journey, and Dokken were cut from the same cookie-cutters that gave us Good Charlotte, Linkin Park, and Puddle of Mudd.
