There are quite a few albums out there that are not easy to get into or for some people they will never be able to enjoy, lots of experimental stuff could be describe like that. However many of these projects are loved by a select group.
This mix means that anyone who looks at a score for a record like that will probably see something in the 50s/60s/70s and may ignore it looking for something with a higher score, but if there was a stamp/mark that could be applied to albums with a large number of very high and very low scores it might let them know that this is the kind of album that people love or hate and not just something that’s a bit middling.
It would even be interesting to be able to search for albums that specifically are hard to get into, but very rewarding after numerous listens as well and this idea could make that a little easier.
