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.
Big Lipped Alligator Moment: Some tracks off his older albums are pretty out there, IE, Something More, from Don't Be Scared which is a 3 minute long audio collage of various noises, background chatting, etc. Also, the random keyboard fills from the Fun album.On the song "Catie", also from Fun, Dan casually burps into the microphone.
Mainstream Obscurity: He is possibly one of the most well known Outsider Music artists in existence and has gained some fame in alternative music circles, but you won't find him in the hit parade soon, left alone a household name with the general public.
