Spotify, Netflix and more will be linkable and playable directly through Facebook.
One of the really nice things about Facebook is the way it plays so friendly with YouTube. Just copy and paste the address of the YouTube video and bam - you've got an embedded video that any of your friends can look at and play.
The newest update to Facebook is going to make it possible to do that same thing with Spotify, Netflix, Dailymotion, Blockbuster and other media services in addition to cooking sites, exercise sites and more.
Check out the video from Facebook for a quick overview and the video from Spotify for a slightly more in depth take on what's going on.
On a disappointing note, Netflix is still up in the air for customers in the US, since there's a bit of confusion on the legality.
