Quirky singer-turned-actress Björk wants to set the record straight: Rumors of battles between her and acclaimed Danish director, Lars Von Trier, on the set of Dancer in the Dark were greatly exaggerated.

The iconoclastic Icelander tells TV Guide Online that she walked off the production for just a day and, contrary to reports, it had nothing to do with any difficulties in playing down-and-out factory worker Selma Jezkova. Björk, who won a Best Female Performance award at the Cannes Film Festival for the role, says her spat with Von Trier was all tied to control over the music she had composed for the film.

"It wasn't like I wasn't going to come back," says Björk, who was miffed when Von Trier refused to give her final approval over the music mix and soundtrack packaging. Eventually, the director relented and production resumed. "It was worth it," she says. "I wasn't going to hand my music over and just go home. I can't do that after 20 years of doing music."

For Björk, music is everything. In fact, she says she could shrug off Von Trier's many extreme close-ups on her sleep-deprived face ("When it comes to visual vanity, I don't really give a s--t") but she was completely thrown any time she hit a wrong note in one of the movie's musical numbers.

Despite the accolades for her Dancer performance, Björk isn't anxious to return to the big screen. "Right now, I feel very strong about focusing on music," she says. "I think quite a lot of people out there can do excellent films, but I get really depressed when I go to Tower Records — I don't think there are a lot of good CDs there."

If Björk had listened to her peers, she never would have done a movie in the first place. "All the people that I work with, my creative family that I've worked with since I was a teenager, all said, 'Don't do it. It's ridiculous.' But I had to do this, you know? I didn't know why at the time, but I have to follow my instinct."
