Maybe you should check them out; they're not obscure at all. Evergreen has one of the great Echo & The Bunnymen singles on it (Nothing Lasts Forever) and Time Out Of Mind seems to be a Bob Dylan album that even non Dylan fans appreciate. They're both far more "visible" (TOOM won three Grammys, not that that means anything) than most of the albums posted here.
Who gives a fuck about lists? If we went by lists, Sgt. Pepper would still be the greatest album ever (and Pet SounRAB the second best).
And there is no such thing as objectively rating an album outside of sales, which are meaningless anyway. If we're going by how many people like an album, you should really be listening to the Eagles, Michael Jackson, Elvis Presley, Garth Brooks, etc. if you want to hear "objectively great" music.
