I had to do some revising of my list because I missed quite a few of my favorite bands and I wasn't happy with the order I put them in. I am doing a top 25 [band (fav. album/fav. song)] and a top 10 non-metal bands/performers. As for being in order I tried but unfortunatly I can only prioritize the first 7 (I have a hard time putting one band ahead of another because I like them both in different ways):

1. Iron Maiden (7th Son.../tie Wasted Years and Strager In A Strange land)
2. 4 way tie because the bands are intertwinded in a way

a. Savatage (Edge Of Thorns/Miles Away)
b. Circle II Circle (Burden Of Truth/Heal You)
c. TSO (Lost Christmas Eve/What Child Is This?)
d. Jon Oliva's Pain (remains to be seen, I only have Maniacal...)

3. Nightwish (Oceanborn/Sleeping Sun)
4. Saviour Machine (Legend III:II/American Babylon)
5. Kamelot (Karma/Forever)
6. Helloween (tie Time Of The Oath and Better Than Raw/Keeper Of The Seven Keys)
7. Dream Theater (tie Images & Words and Awake/Scarred)
Iced Earth (Dark Saga/tie Burnt Offerings and Dante's Inferno)
Shadow Gallery (Tyranny/Crystalline Dream)
Ayreon (Human Equation/Day Eleven: Love)
Symphony X (The Odessy/Acolade II)
Tourniquet (Microscopic View/Erratic Palpatations Of The Human Spirit)
Rob Rock (Garden Of Chaos/Millennial Reign)
Leaves' Eyes (Vinland Saga/Legend Land)
Therion (Lumeria-Sirius B/The Khlysti Evangelist)
Rhapsody (Symphony Of Enchanted Lands/Power Of The Dragon Flame)
Dio (Magica/Mystery)
Blind Guardian (Nightfall In Middle Earth/A Dark Passage)
Metallica [pre-Load] (Master Of Puppets/One)
Testament (The Ritual/Return To Serinity)
Judas Priest (Jugulator/Night Crawler) [very subject to change on fav. album]
Thunderstone (Tools Of Destruction/Virus)
