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.

Signature Song: "1985" or "High School Never Ends". "Girl All The Bad Guys Want" is also one of their more popular songs, being their first song to really hit big.
