The music company affiliated with “American Idol” producer 19 Entertainment is suing Sony Music for alleged unpaid royalties for the show’s stars, including Kelly Clarkson and Carrie Underwood, reports Deadline.com.

The breach of contract complaint from 19 Recordings is seeking compensatory damages of more than $7 million, pre- and post-judgment interest of “at least 3 million,” and legal and organizational costs, the story notes.

“It was very important to my clients to protect their artists, and we look forward to pursuing this,” attorney Richard Busch told the publication.

The lawsuit alleges that Sony failed to properly account and pay royalties, and also claims the music company wouldn’t allow 19 Recordings to conduct an audit.

“Despite 19′s best efforts, Sony has refused to correct its underpayments to 19 and has forced 19 to file the instant suit in order to recoup the amounts Sony has underpaid 19 as well as recover any additional damages such underpayments have caused 19,” the lawsuit claims.
