Lyric: KITSUNE of METAL GOD / Music: KITSUNE of METAL GOD / Arr.: Yuyoyuppe
Usually, this is the opening tune of BABYMETAL's concert.
BABYMETAL DEATH (We Are BABYMETAL)
B x A x B x Y x M x E x T x A x L DEATH!!
[i] The letters "DEATH" only means "to be" (= DESU/DES_).
The official lyric really consists of only the above one line. Maybe the staff thought too many "DEATH"s are inappropriate.
The Japanese word "desu" (です) is a copula (= to be). The Eastern Japanese almost drop "u" of this word, so the word "desu/des" sounds like "death". And someone started writing "DEATH" instead of "です" (desu). It makes sense only where the Japanese word "desu" is expected to come. The title "BABYMETAL DEATH" means only "We are BABYMETAL." No relation to the death itself.
I'm not sure of its origin, but I saw long before such a character as a vampire or a death metal singer in a comic and all his "です" (desu) were replaced with "DEATH" to emphasize his character. With such an air, it works well. Without such an air, it probably doesn't work.
[ii] Is This Death Metal?
There is a genre named "Death Metal". The sound of this tune seems to fall within that genre, and the lyric writer may have put many "DEATH"s to emphasize the Death-Metal-ness. It might be alright to use many "DEATH"s without thinking of death if some of Death Metal bands also chose their style just to differentiate themselves rather than driven by the feeling about death. But I don't know the Death Metal well.
