(AllHipHop News) Pharrell Williams had an outstanding 2014. His single “Happy” was a worldwide hit and earned the Virginia native an Oscar nomination. He also teamed with Uniqlo for an exclusive collection, but it seems another noted collaboration from last year did not turn out the way The Voice coach had hoped.

Pharrell served as executive producer of T.I.’s ninth studio album Paperwork. During an interview with GQ, the Grammy-winning producer expressed his frustration with the project.

“I wasn’t happy about the T.I. situation,” said Pharrell. “They did that record hoping for radio play, and they got nothing out of it…. Great, you got your No. 1 Hip Hop song. But what does that do for your sales?”

Besides serving as e.p. for Paperwork, P also produced the songs “G S**t,” “Oh Yeah,” “Light Em Up” and the title track.

Tip’s album debuted at number 2 on the Billboard 200 with opening week sales of 80,000 units. The album single “About The Money” featuring Young Thug peaked at number 42 on the Hot 100 chart and number 10 on the Hot Rap Songs chart.

“You must find ways to reinvent yourself in order to remain relevant. And who better to help me than someone as passionate and talented as Pharrell?” stated T.I. back in September. “He found a way to bring a colorful, left-field approach to my blue-collar celebrity. Between his wings and my anchor, we balance each other out. That duality is what makes [Paperwork] unique.”
