Full albums are out there, but I only post NZBs for things I think will be wanted that hasn't been posted to death.
This is why you see me post Mastermix issues (they're essential for DJs).
I do see a lot back catalogue stuff by the likes of SOAD, Disturbed, Foo Fighters and lots of general death metal, but hold back with their NZBs cos they're always being posted.
A few groups to try off the top of my head:
a.b.mp3.2000s
a.b.m.full-albums
a.b.m.complete_cd
