Why? If lots of people have this down as their favourite album of all time (or top 5, top 10, whatever) then it’s not like they’re wrong? It’s intrinsically subjective.
For sure, if someone told me they thought, I dunno, Royksopp’s Melody AM was their favourite album of all time, I’d maybe ask if they’d explored more (gulp) experimental forms of electronic music because they might find things they like even more. But if a bunch of folk on here or Pitchfork, who are presumably actively engaged in discovering lots of music, want to fawn over an album, then why does that come across as sickly or forced?
Of course, anointing it the greatest is a different matter, but I don’t think most of the folk fawning over it here are doing that.
