The collaboration is called I'm Not Yours and is Jolin's first attempt at composing. It's not featured in 呸 PLAY so maybe since it has an MV it will be released in a repackage... Lyrics are a mix of Chinese and English, and Namie sings a little in Chinese.

EDIT: I'm not yours confirmed to be in 呸 PLAY according to Jolin's Fans Club.
