I have some Waychtower mp3s already but I want to keep my Power Metal thunder volumnes fairly pure. I want only Power Metal stuff. if you look through the songs you will see hardly any deviation from Power Metal. No prog metal. No growls! No screams!The only slight deviation I had was with annihilator which is more thrashy. But I consider the rest to be more or less straight Power Metal, be it either the US style which is more heavy or the Euro style which is more cheesy or melodic. i enjoy both a lot so I mix up CDs with both styles so that i can never get bored of the CDs if I listen to them in the future. I think Watchtower is a little too thrashy and proggy for inclusion though it is very good aprt from the godawful vocalist!
