Paranoid, OM, Reign In Blood, South Of Heaven, When The Kite String Pops and Metal Storm are 10s for me.

Unison Life is still a 10 for me.

Idk, the Moonlight Sorcery album last year was a 10 for me. I have literally come close to playing that album every week this year. Sometimes you just find something new that speaks to you.

Feel like nothing new can be a 10 these days, nothing new can give you the same massive feelings an older album that was special to you in some way in the past.

i'm a 10

9.5 rounds up to 10, so a 10 album can still have very very minor flaws.

I usually just save a 10 for an album that means something to me and makes me want to keep coming back to it over time
