Beating Pandora to the punch, iHeartRadio has just launched a Windows 10 app that takes full advantage of Microsoft's Cortana virtual assistant. So, in addition to streaming music and radio stations from the app the usual way, you can also shout commands at Cortana to spin up some tunes. (Yes, it also works with Cortana text search.) It also packs in Live Tiles support, allowing you to make your favorite songs or artists accessible right from the revamped Start menu. The new app could be a smart way for iHeartRadio to add to its user base, which already clocks in at over 60 million people. It's surprising that Pandora still hasn't delivered a dedicated Windows 10 app yet, so iHeartRadio might be able to satisfy some of the demand for streaming radio on Microsoft's new OS.
