(CNN) -- An Australian woman pleaded guilty Thursday to fatally stabbing her boyfriend because he objected to her listening to Bruce Springsteen's music.

Bruce Springsteen is an award-winning American singer-songwriter.

The national news agency, Australian Associated Press, reported that the Supreme Court in the city of Brisbane sentenced Karen Lee Cooper to eight years in prison.

Cooper told arresting officers she "just got tired" of her boyfriend, Kevin Watson, bossing her around during their two-year relationship.

"I couldn't even play Bruce Springsteen on my stereo. Can you believe that? Can you believe that?" Cooper told police, according to the Courier Mail newspaper.

Later, in a formal police interview, she repeated her claims: "I mean, who doesn't like Bruce Springsteen? I am 49 years old and I want to play my own music."

Springsteen is an award-winning American singer-songwriter, best known for his lyrics about the struggles of the common man.

The couple had been drinking at their rental home the night of the stabbing two years ago when they began arguing over Cooper's choice of music, the Australian Associated Press said.

Cooper's lawyer told the court she experienced a "brain snap." She ran to the kitchen, grabbed a knife and stabbed Watson, 49, after he said he didn't want her to listen to a Springsteen CD, the newspaper said.

Cooper took a handful of pills before calling police. She told officers she hoped the pills would kill her before they arrived.

According to the press reports, Cooper regretted the stabbing and did not think her boyfriend deserved to die. E-mail to a friend
