Rick Astley/YMMV


 * Crowning Music of Awesome / Nightmare Fuel: Listen to "Lights Out," but ignore the lyrics. Now, listen to it again, focusing on the lyrics.
 * Ear Worm: Lots of his songs.
 * I Am Not Shazam: Thanks to the Rick Rolling meme, casual people tend to refer to Astley as "Rick Roll" or calling the actual song "Rick Roll".
 * Memetic Mutation: And how!
