It is and it isn't. The song is actually a Vocaloid song originally. The creator of the original has two more songs that they made. Both have a sort of similar feel. I actually love all three and was considering nominating all three. The version I picked for The Happiness and Peace of Mind Committee is my favorite English cover.

These are both in Japanese and the singer is a Vocaloid rather than a person, but they are the sequels to the original Vocaloid version of The Happiness and Peace of Mind Committee.
