On-demand music service Rdio yesterday went live with new Unlimited Family plans that will allows users to combine up to three Rdio Unlimited accounts into one billing plan.

Rdio users can add up to three accounts to one plan for a discounted subscription rate. Two accounts cost $17.99 per month, a 10 percent savings off the regular Rdio Unlimited monthly rate of $9.99; three accounts cost $22.99 per month, a 23 percent savings over the regular rates.

With the new plans, each user can download their own songs and create their own login and playlists. Rdio currently boasts a catalog of over 10 million songs.

Each account can be accessed across Rdio’s list of compatible platforms, including web, Mac or PC desktop client, mobile devices such as iPad, iPhone, Android, BlackBerry and Windows Mobile 7, in-home devices like Sonos and Roku, and in the car via Pioneer AppRadio.

Rdio offers single accounts for $4.99 per month (web access only) and Rdio Unlimited for $9.99 (web, desktop, mobile, offline, home and car). The company’s single account offerings are in line with competitors such as Rhapsody and the recently launched Spotify, which also offer $4.99 and $9.99 prices for web-only and multiple access points respectively.
