MarketWatch: Spotify is finally rolling out its video product to the masses. The Swedish music-streaming service plans to introduce video content on its Android app starting this week, followed by the iOS app by the end of next week in the U.S., the U.K, Germany and Sweden. “We are at the end of a journey of testing. We are going out effectively as planned. Our goal was largely to get a wide breadth of content and experiment and test.”
