For streaming music services like Spotify, Deezer and the rest, the ability to ‘cache’ (i.e. download) music for offline listening on mobile devices has become a standard feature. It’s been a touchier issue in the world of YouTube and online video, with Google not happy at all with apps that rip YouTube videos into downloads. Things are shifting though: it looks like YouTube is launching an offline-cacheing feature for its YouTube mobile app this November. “This upcoming feature will allow people to add videos to their device to watch for a short period when an Internet connection is unavailable,” explains YouTube’s Creators blog, aimed at people running channels on the service. “So your fans’ ability to enjoy your videos no longer has to be interrupted by something as commonplace as a morning commute.” For now, Google is keeping further details under wraps, but we’ll be interested to see how many music videos allow the feature (if, indeed, they have a choice).
