These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.

Ear Worm: The songs quoted (and referenced in the title) of each story — they're considered classic rock and roll, and some are well known enough that most people (in America, anyway) know the words.
