Lyric

"Good bye" is a song first introduced by the talent Matsuko Deluxe during the live broadcast of TOKYO MX's information program "Goji ni Muchuu!" on July 1. This song was created to realize Matsuko's proposal from the June broadcast to use death metal as closing music.

The experiment took place at the supermarket chain "Akidai," headquartered in Nerima-ku, Tokyo. The well-known president, Hiroshi Akiba, commented, "At our store, we stop the background music and dim the lights at closing time," showing enthusiasm for adopting a new closing song. The experiment was conducted at the Akidai Sekimachi main store in Nerima-ku, and "Good bye" will be played at closing time for one week only.
