Spotify's family plans went live this week, and today Rdio reduced the cost of its subscription sharing to match. The latter streaming option revealed new rates for spreading access to its massive library amongst your relatives at $5 for each additional person. If you aren't looking to do the math, that's $15 for two, $20 for three, $25 for four and $30 for five. Those prices look familiar? Well, they should: they're now exactly the same as Spotify's sharing plans that also save you 50 percent over the regular monthly cost for each additional subscriber. Rdio began offering family options back in 2011, with two accounts starting at $18. They were initially limited to just three people, but the company bumped the allowance to five last summer.
