There are too many (like most decades) for me, included but not limited to:
Thriller – Micheal Jackson (how this wasn’t the second post is beyond me)
Purple Rain Prince, perhaps not as good as Dirty Mind, but the man is so prolific there’s still Sign O the Time and Parade in the eighties
Graceland – Still astonishing
Murmur – REM They released what 10-12 albums in the eighties? pick one they’re nearly all solid…Maybe Green?
It Takes a Nation… P.E.
Dolittle
Scary Monsters and Super Creeps.
Faith – Why is he sniffing his arm pit on the cover though?
Dare.
Psycho Candy – If nothing else it annoyed my parents.
Oh God, the more I think about it, the more there are, some excellent suggestions already though
