The album I've listened to most of the years would be Wiseblood by Corrosion of Conformity I'm pretty sure.
Following that would probably be:
DJ Shadow - Endtroducing
and
Cirrus - Counterfeit
A Love Supreme by Coltrane is catching up pretty fast, but I've only owned that for a little over a year so its got a-ways to go to reach the others.
