I'm not really good at explaining my opinions, though, so I'll be a bit brief. I'll do my best to convey my emotions to you, though.
lice Cooper - Raise Your Fist And Yell: nice, kinda funny.
Blind Guardian - Somewhere Far Beyond; Tokyo Tales; Imaginations From The Other Side: still cool.
Death - Symbolic: relaxed-cool.
Dio - Holy Diver (+ Live): relaxed.
DragonForce - Valley Of The Damned; Sonic Firestorm; Inhuman Rampage: nice because it's so bloody fast
Dream Evil - Dragonslayer; United: cool.
Feinstein - Third Wish: OK, but a bit tame.
Gamma Ray - Somewhere Out In Space: really cool.
Helloween - Keeper Of The Seven Keys Part I and II: also really cool. Funny too. I didn't like The Legacy as much, though. Don't know why. Maybe it's the contrast with the other two albums.
Iced Earth - The Dark Saga: I didn't really like it. I think it's more because of the character of the album (at least, what I perceive of it) than the music itself.
Iron Maiden - Somewhere In Time; Seventh Son Of A Seventh Son; The Number Of The Beast: nice.
Judas Priest - Painkiller: like it.
King Diamond - Abigail; Them; The Eye: don't really like it.
Manowar - The Triumph Of Steel: kinda boring.
Megadeth - Rust In Peace: nice.
Metal Church - Blessing In Disguise; The Human Factor: nice.
Overkill - Horrorscope: nice.
Ozzy Osbourne - Tribute: nice, a bit in the same way as Alice Cooper.
Rhapsody - Legendary Tales; Symphony Of Enchanted Lands; Dawn Of Victory; Power Of The Dragonflame: a bit too much Hollywood. And not heavy enough.
Saxon - Heavy Metal Thunder; Lionheart: cool.
Slayer - Seasons In The Abyss: OK.
Symphoney X - The Odyssey: OK.
Virgin Steele - Invictus: nice
W.A.S.P. - W.A.S.P.: OK.
Hope you can see some pattern in that
