anti-nightcore 

Anti-Nightcore is any song that is created by slowing down the melody (sometimes), a slow rhythmic beat (usually), and ALWAYS making the pitch lower than the norm. Almost all the anti-nightcore music genre are original songs made into anti-nightcore by BOTH anti-nightcore AND nightcore fans.

(Similar definition to nightcore.)

"Dude, have you heard this awesome new nightcore song?"

"Huh?"
"It's the opposite of nightcore."
"So you mean it's slowed down?"
"Exactly!"
