Jay Z to perform rare songs to promote Tidal service

LOS ANGELES (AP) -- Jay Z is breaking out his B-sides to hype his fledgling music streaming service.

The rap mogul announced plans Wednesday to unearth songs he hasn't performed in a decade -- or ever -- at a free New York concert. The performance will be held May 13 and subscribers can submit a playlist on the service to win tickets.

Jay Z took to Twitter on Sunday to defend Tidal's slow start. He co-owns the service with Beyonce, Rihanna, Madonna and other artists. He said Tidal currently has 770,000 subscribers.

"The iTunes Store wasn't built in a day," he wrote. "It took Spotify 9 years to be successful. We are here for the long haul. Please give us a chance to grow and get better."

The concert will be streamed on Tidal.com.
