So it gets a 5 musically but then you've paid attention to all the detritus surrounding the album/ band and given it a 1/10.
In fairness, I can fully sympathetise with that.
Context has a lot to do with it. I opted out of scoring Revolver, but my own sentinent would have been exactly the same with that one. Benny would do it with Rush/Biffy. You do it too, with what you associate with albums culturally at the least. It is all part of it, and imo is quite normal.
