is the 2nd single by Berryz Kobo × Cute (pronounced Berikyū), a collaboration unit between the Japanese idol groups Berryz Kobo and Cute. The single was first released for paid download on April 28, 2012; the CD single was released on June 20, 2012. Background The title song is a mix of two previously published songs, Berryz Kobo's "Because Happiness" and Cute's "Shiawase no Tochū" from their 2012 albums. Both tracks were intentionally composed and produced by Tsunku to form a new song when played simultaneously. The trick was originally scheduled to be announced at a summer Hello! Project concert, but was uncovered by fans in mid-April. The song became a hot topic on the Internet, and a set of the three tracks, "Because Happiness", "Shiawase no Tochū ", and "Chō Happy Song", was hastily released as a digital download single on April 28. The CD single will be released on June 20. It will contain a new arrangement version of the title track. The CD single will be available in 5 versions: Regular Edition and Limited Editions A, B, C, and D. The Limited Editions A and B will include a bonus DVD; all the other editions will be CD-only. As usual, all the limited editions will be shipped sealed and will contain a serial-numbered entry card for the lottery to win a ticket to one of the single's launch events.
