The romance genre is so enormous it leads to lot of "genre stuffing"... basically, shoehorning a romance book into other categories simply as a means of increasing exposure or Amazon rank.
I often find whenever I go searching through lists like top 100 books in a specific genre, invariably the list is overrun by romance titles with the barest of passing nods to the genre. Because the industry is so cutthroat, many authors now use this tactic to achieve higher rankings, disregarding the actual readers of a genre who must now wade through books unrelated to what they are searching for.
Romance novels certainly have their place in the world, don't get me wrong... but as far as The Audiobook Review goes, we won't be including them. Books that clearly fall primarily into the romance genre but are trying to pass themselves off as something else will not be accepted.
