On its blog today, Rdio announced that it will now support up to five people on its family plan. Previously, only three customers were able to buddy up on the music-streaming service, with monthly pricing set at $17.99 for two users and $22.99 for three. Fees for two and three users will remain the same, while four members cost $27.99 and maxing out with five listeners will set you back $32.99 per month. If you already have an account and want to get your sibs in on the actions, head to your Rdio settings and select "Unlimited Family." From there, you can invite the family to sign on.
