Best album of the 80s?

[big screen satellite]

i'm a stickler for rules on these important topics, and as good as London Calling is, it was originally released in (very late) 1979, and hence is an album from the 70's...

i know it has the early 80's feel about it, but it is clearly dated 1979 (and was obviously recorded during '79,

it's kinda like the Stone Roses album which was released in 1989, but has more of an 1990's feel to it... when we do the 90's thread, on this - i'm sure some people will list that in there too...

its a difficult question because anything released in 1979 obviously lasted beyond the one year and was played during the 80's, but technically the Clash are a band from the 70's, who went on into the 80's...

picky i know, but hey its the 80's baby and well its just gotta be right...
