POTW: Katy Perry, Gaga, Bieber and more '2011 Billboard Music Awards' Finalists
Ke$ha, nominated for six 2011 Billboard Music Awards, gets sweet at the Sugar Factory American Brasserie on May 7, in Las Vegas.

It's no secret that rock 'n' roll has fallen behind chart competitors such as pop and hip-hop in recent years, but one unlikely artist says she's ready to return the genre to its former glory.

"I feel like I don't necessarily agree, but people say that rock and roll is dead, and it is my mission and my goal to resurrect it in the form of my pop music," Ke$ha told MTV News. "That's the goal. We'll see what happens. That's a very ambitious and lofty goal, but that's my goal."

While critics of the glitter-loving singer might call that a "Mission: Impossible," Ke$ha is starting 2012 by showing her range: her stripped-down cover of Bob Dylan's "Don't Think Twice, It's All Right" will appear on Amnesty International's "Chimes of Freedom" tribute compilation, due Jan. 24. The acoustic effort is far from the club-centric singles that led 2010's "Animal" to the peak of the Billboard 200.

"You might hear a little bit more vulnerability on the next record 'cause I have realized just from this Dylan cover coming out that it can be such a strength and a nice balance to humanize the other side of my personality," Ke$ha said. "I have learned over the past three years of doing this that being vulnerable doesn't mean you're weak. I very much want to be seen as a strong woman, but I realize that vulnerability can also be a strength. So on my next record, you are going to hear probably a little more of that. I'm not going to make an acoustic, sad entire record."

She added that she and producer Dr. Luke have been working on new material independently and will "go into the studio" together this month to begin recording.

In the meantime, fans of Ke$ha's less sensitive side can hear her in her element on the December-released second "Sleazy" remix, which landed Lil Wayne, T.I., Wiz Khalifa and another appearance by "Sleazy" remix veteran Andre 3000.
