Promotion

edit

The single had two tie-ups: "Makenai Kokoro" was used as the theme song of the television drama Gakeppuchi no Eri: Kono Yo de Ichiban Daichi na 'Kane' no Hanashi, while "Day By Day" was used in commercials for Avex Artist Academy.[2] Band member Takahiro Nishijima featured as an actor in the seventh episode of Gakeppuchi no Eri.[citation needed]

Single contents

edit

Six versions of the single exist: a CD only version, two DVD editions, and three Mu-Mo store exclusive versions.[1] DVD edition A featured the music video for the song, while DVD edition B featured a documentary on the making of the music video for their previous single "Aitai Riyū."[1]

All versions feature "Makenai Kokoro" and "Day By Day", while only the CD only version features the group's cover of H Jungle with T's 1995 number 1 single, "Wow War Tonight (Toki ni wa Okose yo Movement)". The Mu-Mo exclusive versions each feature one of three live talk tracks, where the band members discuss the time since their debut in 2005.[1]
