1. Nice back - Silver Side Up
2. Jay Z and Linken park - Collision Course
3. Eminem - Curtain Call

In no particular order:
Iron Maiden - Seventh Son of a Seventh Son
Iron Maiden - Powerslave
Judas Priest - Painkiller
Nightwish - Century Child
Queensryche - Operation: Mindcrime
Led Zeppelin - IV
Helloween - Keeper of the Seven Keys part 2
Ayreon - Universal Migrator
Avantasia - The Mystery of Time

and too many others to list. I couldn't even pick a 10th album, since I would be leaving out so many great albums from bands and artists I love.

Some great choices. Was contemplating some Maiden for my list (Piece of Mind probably... or Brave New World), just not enough space though.

What made you go for The Mystery of Time over all the other Avantasia albums?

Just the first one that came to mind from Avantasia to be honest. I could have just as easily picked at least three others from them, but just wanted one to represent them.

I see some incredible picks from everybody here! Thumbs up!
Here's my top 10:

1. Judas Priest - Painkiller
2. Yes - Close to the Edge
3. Madonna - Confessions on a Dance Floor
4. Miles Davis - Kind of Blue
5. Buena Vista Social Club - Buena Vista Social Club
6. Charles Mingus - Mingus Ah Um
7. Kraftwerk - Trans Europe Express
8. Alice in Chains - Dirt
9. Paul Simon - Graceland
10. Metallica - Master of Puppets

no particular order

placebo - sleeping with ghosts
queens of the stone age - lullabies to paralyze
deep forest - deep forest
rammstein - sehnsucht
korn - korn
alice in chains - dirt
burzum - burzum
snap - world power

I'll need to think about this one. More to come.
