Legendary band, btw. Gotta go with Stained Class(classic metal at its finest, catchiness + unforgettable melodies), Defenders would be my second favourite, and Painkiller my third(Painkiller is pretty much a lesson of how balls-out power metal shoud be done)
Well, I'm not gunna come out and say they're a talentless bunch of tea sipping wankers; but if I did, it just wouldn't be my cup they were sipping from.
