most listened to cd in your collection

Recently, probably Aqualung by Jethro Tull - although if you only mean metal it's probably been "Scars of the Crucifix" by Deicide.
All time most listened, "Appetite For Destruction" without any doubt, and it's STILL the best album I've ever heard.
 
I've been getting ready for Ozzfest which you'll be able to see with some of what I've been listening to lately

Judas Priest-Painkiller

Judas Priest-Screaming For Vengeance

Judas Priest-British Steel

Halford-Insurrection

Slayer-Soundtrack To The Apocalypse disc 1

Monster Magnet-Monolithic Baby

Black Sabbath-Vol. 4

Slipknot-Vol. 3 The Subliminal Verses

Anything Ronnie James Dio sings on as usual (Favorite singer of all-time)

Overkill-Horrorscope
 
The CD that I have listened to the most would be either Immortal - Sons of Northern Darkness, or Cradle of Filth - Cruelty and the Beast. I used to listen to Cruelty a lot, usually to aid in falling asleep. :dopey: So I actually didn't listen to the whole thing often, but it got a lot of play time. :D

Darkthrone - Ravishing Grimness has been occupying my players a lot lately, it may soon be the most listened to CD.
 
anthrax - madhouse

pantera - the great southern trendkill. :Spin:
 
Tristania's 'Beyond The Veil' has had a lot of play this year for me for no apparent reason.
Oh yeah...it's really, really good. :worship:
 
Whoa...Guess I can bar it down to 6 haha:

Metallica: ...And Justice For All
Death: Leprosy/Human
Symphony X: V
Manowar: Battle Hymns
In Flames: Lunar Strain
AC/DC: TNT

I listen to music as much as I can, so it's hard to follow.
