As much as I liked "The gates of Oblivion" and "The Hall of the Olden Dreams", as little I like this one. To me the Album seams to be a kind of odd compilation of different styles and genres. A patchwork with to common ground. "Just Rock" is some 70's rock with some 80's string overlay. If you like Power Metal, go for the for mentioned albums. Also very good are in this genre are Hammerfall, Clawfinger, In Flames, Rammstein or my current favorite, Dragonforce.
