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: Except for their relatively small dedicated fanbase, everyone remembers either "Gay Bar" or "Danger! High Voltage!," but nothing else. Some people also remember "Radio GaGa", which was much more popular in the UK.
Squick: Nude grandma in the "Body Shot" music video. Fat sweaty, topless men from the same video.
"Infected Girls," which is about humping STD-infected girls, because who needs protection when you're already infected?
"Showtime" is probably a subversion, depending on interpretation and taste in condiments. At the end of the song, there is a quiet, wet squelching sound. Out of context, it's unexpected, but it makes sense when you consider all the times Dick Valentine has said, "put a little mustard on it".
