For the various series, Columbia has taken various popular vocalists of anime songs and brought them together in a group called Project.R (the "R" stands for "Ranger"). The opening and ending themes and the insert songs are performed by individual members or a subset of members of Project.R. Several songs are performed by long standing theme song singers who are not included as being members of Project.R (the songs are composed by Project.R members, though). These artists are Shinichi Ishihara, MoJo, Akira Kushida, Takayuki Miyauchi, Koji Onoda, Ichirou Mizuki, and Make-Up.
Oshitani previously performed the B-side "Over the Star" on the Dragon Ball Z Kai single "Yeah! Break! Care! Break!" before performing as one of the many vocalists on the Gokaiger ending theme.
Zetki is a Japanese jazz band fronted by Hideaki Takatori on vocals and includes Hiroaki Kagoshima on piano. They had performed the backtrack on the Samurai Sentai Shinkenger ending theme.
Miyaki had written and arranged various insert songs in Gekisou Sentai Carranger and also composed and arranged the Hurricaneger and Gekiranger soundtracks; he arranged the Gekiranger ending theme.
Yamashita was a composer and arranger on the Abaranger soundtracks as a member of Kentarō Haneda with Healthy Wings and made his composing and arranging debuts on the Magiranger soundtracks.
Kameyama was a composer and arranger of various insert songs in Carranger, Megaranger and Seiju Sentai Gingaman before composing and arranging the Mirai Sentai Timeranger and Dekaranger soundtracks.
The single of the opening and ending themes of Engine Sentai Go-onger reached #4 on the Oricon Weekly Rankings Charts in its first week, selling 22,000 records. It is the first theme song single for any Super Sentai series to reach the Oricon's top ten list, reaching #3 on its first day of sale, March 19, 2008, and remaining in the top 20 for four weeks.[1]
