I sometimes feel that way, but mostly not because I like albums and think they are excellent units in music history

Also - obvious point, but songs on an album are often more artistically similar to eachother than to songs from other albums by the same band/artist.
I still understand where you're coming from. I think what kills discussion more for me is that when it comes to music, I'm generally respectful of other people's opinions and that doesn't really lead to a lot of interesting debate. If I thought the quality of music was objective rather than subjective, I'm sure I would be more interested in other people's opinions about it.
I like Kate Bush, but I don't really care if person X who I don't know hates her.
