denpa  Tag

Denpa (電波) is a Japanese word meaning "radio waves" but these days, it is specifically used to describe a relatively new genre of music emerging quasi-exclusively from Japan and covering some over genres like gamewave, chiptune, bitpop, akibapop and to a certain extent, JPop.

From Wikipedia:

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 doujin 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.
