I love test screenings. Some directors don't, I know. But I love it. I think it's because I come from the theatre and in the theatre, previews are where you really have to listen to the audience and really feel how they're responding. I found our test screenings incredibly useful.
The only person I've worked with on my album was Kanye. And between the stuff that I've done and the stuff that he's assisted on and produced for me for this album, I don't even need anything else.
