Pandora acquired stream service RDIO for $75 million in November… and now, it’s being shut down.

Subscribers were greeted with a message this week on its website, which announced the news.

“Rdio is being acquired, and the service is shutting down worldwide on December 22,” the statement reads. “We’re excited to bring great music experiences to even more listeners in the future as part of the Pandora team.”

“We’re honored to have connected you with the music you love. We know you want to find a home for that music, so we’re providing ways for you to take it with you.”

RDIO is no longer accepting new registrations, as it appears Pandora is using the service to likely bolster its own service with on-demand streaming at some point in the near future.
