Rdio has launched a free personalized radio stations option within its iOS and Android apps. This is a more controllable version of the You FM feature added back in August.

Like iTunes Radio, you can’t choose a specific artist or track, but you can create a radio station based on a song, artist or genre and then listen to the stream Rdio creates based on your selection. Unlike iTunes Radio, Rdio’s free streaming service is ad-free, at least for now.

New subscribers also get a 14-day free trial of the Rdio subscription service, allowing you to play specific tracks. Once the 14 days end, however, you’ll revert to radio stations only unless you sign-up at $9.99 a month to keep the paid service.

Rdio is a free download on iTunes.
