If you've checked into Rdio's website this afternoon (and are a web or unlimited subscriber) you've probably noticed a message prompting you to try out the "new Rdio." Clicking on it will take you to the redesigned website that the music streaming service has rolled out today -- something the company claims is "faster, simpler, and more social." That includes a completely overhauled layout that puts it slightly more in line with the likes of Spotify and iTunes, and social networking features that are brought to the fore, including a new "People Sidebar" where you can see who's online and what they're listening to (along with suggestions of people to follow). You can also now simply drag tracks to the People Sidebar to share them with friends, or drag entire albums to add them to a playlist. What's more, that overhaul also carriers over to Rdio's desktop apps, which now mirror the web interface quite closely. Hit the links below to take a closer look or try it for yourself.
