Rdio, one of the more popular streaming music services out there, just announced a new tier of service. For $5.99 a month, you can listen to unlimited ad-free radio on your mobile device, plus 25 on-demand downloads that you can listen to offline.
The streaming radio is the main feature of the new service, called Rdio Select, but the offline songs is a nice touch. You can keep up to 25 songs on your phone at any time, with new downloads replacing old ones. You can replace all 25 songs up to once per day.
You'll also get everything in higher quality 320kbps bitrate. Desktop users will still have ads, though Rdio Select will soon be coming to other devices like the Roku and Sonos.
Check out the full blog post over at Rdio for more information. There's a 60-day free trial available.
