Apple is reportedly securing a deal which would bring a major contributor to its upcoming streaming music service.

The Wall Street Journal cited sources familiar with the matter in reporting that the company has inked a deal with Warner Music to bring the label’s content to a “radio” channel streaming service from Apple. The deal reportedly includes an agreement to pay Warner 10 percent of the service’s advertising revenues.

The rate could help lure labels towards iTunes and away from would-be rival Pandora, which is said to pay labels a smaller percentage of ad revenues.

If true, the report would lend further credibility to the belief that Apple would soon be launching its streaming music service. The company has been said to be planning a service for years, though no official word has come from Apple.

Speculation on the streaming service launch picked up earlier this year when researchers uncovered hidden code in the latest test versions of iOS. The unused components referenced versions of a streaming service from Apple.

Should Apple decide to launch its service this year, the unveiling could come as soon as next week when the company holds its annual World Wide Developer Conference. The presentation is believed to include updates on the latest versions of both OS X and iOS.
