 It was advertised with the tagline "Let's buy the same CD over and over again", referring to the marketing technique used by the management of idol groups to encourage fans to purchase several copies of a CD single.Before the single's release, the music video for "Idol" was uploaded to Bis' official YouTube channel and was met with criticism; the once shocking, punk rock Bis were singing a very typical cute idol song, wearing maid outfits and simpering.However, this video (with its deliberate parody of idol groups) was revealed to be a joke at the expense of their fans.
