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.
Nightmare Fuel: "Unison" is a demo that appears on the 2005 reissue of Remain In Light and it's a catchy, but chilling and eerie song that echoes the lo-fi sound of early Devo. It doesn't help that it opens with a sharp, ear piercing synth note.
Shout-Out: A possible cryptic one in the video to "Road to Nowhere". Around 1:10...the blonde lion mane...the blue-white striped pullover...the annoyed look...you need freeze-frame to confirm she's NOT Kim Wilde.
Tough Act to Follow: The reason the band never played live again after the tour for Speaking in Tongues, as captured in Stop Making Sense. As explained in the "self-interview" available on the DVD, the band would only tour if they felt they had something new to say rather than just supporting a new album.
