SoundCloud was already compatible with Sonos devices, and Android folks had Chromecast integration for awhile now too, but Friday's update means iPhone users with a SoundCloud Go+ subscription can finally stream their entire catalog to a Chromecast connected to a TV or speakers. Multiple users can also control what's on with a shared playback feature. SoundCloud also says they've upgraded their mobile apps across the board and streamlined the whole experience for more consistent playback.
