When Griffin is releasing the BTR deluxe edition album. Gustavo has to hire songwriters but they end up fighting and cannot write the song. So Gustavo writes the song himself. Kendall, James, Carlos, and Logan want to write their own song, Gustavo doesnt agree with them so the boys want Katie to open a health spa in the Palmwoods so they can write the song while Camille and Buddha Bob keep Gustavo busy. In the song writing process, Kendall and Carlos write a song named "Oh" while James and Logan prefer their song called "Yeah", this creates a fight between the members of the group. After the fight, they realize the song can collaborate together and form "Oh" and "Yeah", the song then becomes Oh Yeah and is approved by Griffin. (thetvdb.com)
