There is a set of music and film that I wouldn't call guilty pleasures but I would never recommend to anyone else.
As much as I love Mr. Bungle, no one needs to be introduced to them by me. It's just not the sort of music that is fair to inflict on anyone else. The same goes for Primus.
What I do feel guilty about is a playlist I have called '80s shit I shouldn't like'. Level 42 and Go West. For shame.
