What most of these are are examples of "bad art", which is related to the concept of "ugly beauty". "Bad art" is impactful but the impact seems to strongly differ from the perceived intent of the creator. How important creator intent is to an art objective is highly debated. There is also the issue of how humorous the object is perceived to be in a particular culture, again generally as opposed to the creator's intent. Some of the objects, though, are intentional parodies (pranks, academic illustrations, etc.).Not that they aren't funny, but half of these are worst album titles and not worst album covers.
