The Black Crowes are up in arms over country star Gretchen Wilson's new song, 'Work Hard Play Harder,' which is being used in an advertising campaign for the TV drama 'Saving Grace.' The rockers are accusing Wilson, Turner Network Television, Wilson's label Sony BMG and publisher J Money Music of copyright infringement. Their legal notice alleges that Wilson and her songwriters have wrongfully exploited the Crowes' 1991 hit, 'Jealous Again,' in their ads.

"We find the musical verses of Wilson's song to be such an obvious example of copyright infringement that I expect all parties to reach a relatively quick resolution to avoid litigation," reports Pete Angelus, longtime manager of the Black Crowes.

There is no response yet from Wilson's camp. She has filmed a video for the song, which is being shown in an advertisement on TNT, TBS, truTV and in Regal Cinemas. (Watch it here.)
