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.
Alternate Character Interpretation / Fridge Horror: "Bones" is not officially part of the murder trilogy, but consider this: it's about a guy trying to convince his girlfriend to go down to the beach with him at night, while "Midnight Show" is about a guy who takes his girlfriend to the beach at night and strangles her.
There's a different take on "Jenny Was A Friend Of Mine" in live performances. Sometimes the line "she couldn't scream while I held her close" is replaced with "she couldn't scream while I held her throat". Not always, but it's enough to imply the protagonist might not be the innocent man he claims.
Awesome Music: So much to list. "Mr. Brightside", "Read My Mind" and "Human" come to many minds, although the other songs are all good in their own right.
Epic Riff: "Mr. Brightside" accomplishes this almost instantaneously.
