It's hard to associate Ke$ha with songs about anything other than hot guys, body glitter and partying. But she's defying her usual topics of interest for human rights organization Amnesty International. The singer is one of the many musicians on the org's Chimes of Freedom compilation of Bob Dylan's music, out January 24.

When MTV News spoke with K-Dollar Sign last week about her all-star remix of "Sleazy," she also opened up about switching gears vocally and emotionally for her version of Dylan's classic "Don't Think Twice, It's All Right."

"I mean, I think it's pretty well known that he's one of, if not my most, favorite artists of all time and ... one of the most amazing lyricists as well — the original storyteller," she explained. "So I love Bob Dylan and this was just, like, a dream. When they asked me to do a cover, I was just, like, salivating and going through all my records. It was so fun. It was the best homework assignment you could possibly have." (Source: MTV News)
