Denpa song

A denpa song (電波ソング) is a type of Japanese music that is intentionally strange and catchy. Common features of denpa songs include intentionally off-key vocals, nonsensical lyrics, and an over-the-top tune. Denpa music has grown into a subculture within Japan, forming a significant aspect of otaku culture, and has large numbers of dōjin circles and music artists dedicated to denpa music. Denpa is not a specific genre in itself, but rather an umbrella term for various kinds of music. Alternative terms for denpa music coined in recent times include Akiba-pop (i.e. "pop of Akihabara") and A-pop. The term "Moe song" (萌えソング) specifically refers to denpa music of otaku origin featuring moe themes.
