Remember when Rdio announced their freemium streaming plan was on the way? Well it's here. No ads. No limits. And you don't have to have a Facebook account (if you don't want).
Like the other services, Rdio's free plan only extends to the web and desktop apps. So you still gotta pay for mobile access. And they only have 12 million songs (compared to Spotify's 15 million). But they also have the best UI and design out of any of the services, and it still works with Facebook's Open Graph, so you can annoy everyone with ticker updates. [Rdio]
