Netflix is working on a new audio-only mode.

The company as confirmed testing is underway for the new feature, with some subscribers seeing a 'video off' button at the top of their full-screen player.
As reported by Android Police, this will allow users to listen to shows - such as nature documentaries - in the background.
In a statement, a Netflix spokesperson said: "We're always looking for new ways to improve the Netflix mobile experience for our members.
"We run tests in different countries and for different periods of time -- and only make them broadly available if people find them useful."
Earlier this year, Netflix started testing a feature which would allow users to watch movies and shows at up to 1.5 times the normal speed.
However, the move proved controversial, with filmmakers - including 'Ant-Man' director Peyton Reed - criticising the feature on social media.
He tweeted: "This is a terrible idea, and I and every director I know will fight against it."
Judd Apatow also wrote: "No @Netflix no. Don't make me have to call every director and show creator on Earth to fight you on this.
"Save me the time. I will win but it will take a ton of time. Don't f*** with our timing.
"We give you nice things. Leave them as they were intended to be seen."
