This is a reader's list, so it doesn't count, but I figured I'd post it anyway.
1. The Joshua Tree, U2
2. Appetite For Destruction, Guns N' Roses
3. Thriller, Michael Jackson
4. Born in the USA, Bruce Springsteen
5. Purple Rain, Prince
6. Back in Black, AC/DC
7. The Queen is Dead, The Smiths
8. London Calling, The Clash
9. Disintigration, The Cure
10. Master of Puppets, Metallica
I'm surprised to see 7 and 9 on the list. About London Calling, apparently they're going by the US release dates.
Here is the link to the true list, by the magazine:
