Trivial Tuesday

I'm too lazy to spend much time thinking of a question, so this will probably be pretty easy.

In 1999, Rosa Parks sued a hip-hop group for using her name as the title of a song without permission. The suit was eventually dismissed only to be refiled in 2004 and settled out of court in early 2005. Who was this Atlanta-based duo?

Ready, set, answer...

Update: Congrats to Maine, who knew that the answer was Outkast.
