Agent J (album)

Agent J (Chinese: 特務J) is the ninth studio album by Taiwanese singer Jolin Tsai. It was released on September 21, 2007, by EMI and Mars. Agent J was produced by Lars Quang, Nik Quang, RnG, Adia, Paul Lee, Michael Lin, Paula Ma, and Jamie Hsueh. It was released alongside the film under the same name, which was directed by Jeff Chang, Marlboro Lai, and Kuang Sheng, and it features Kim Jae-won, Stephen Fung, and Carl Ng.

The album received generally unfavorable reviews from music critics, who commented while it retained Tsai's diverse musical styles, it lacked freshness and melodicity. A commercial success, the record sold more than 3 million copies in Asia. In Taiwan, it sold more than 200,000 copies, becoming the year's highest-selling album. Producer Adia won a Golden Melody Award for Best Single Producer for "Agent J", while Andrew Chen won a Golden Melody Award for Best Music Arrangement for the same track.
