YouTube made stars of Justin Bieber and Psi.
It's the go-to site for finding millions of music videos for free.
One billion people visit YouTube.
That's one of out of seven people on the planet.
Now, YouTube wants to get people to pay for that music.
After two years in development, it's launching Music Key.
A subscription music streaming service.
YouTube will be competing with the likes of Spotify, Pandora, and Apple's Beats music.
With one big difference, video.
Tell me that you turned down the man.
For songs that don't have music videos, the tracks play over still images.
YouTube says the available music content will be the same for subscribers and nonsubscribers.
But the $10 monthly fee will get you access to new features.
Like the ability to skip ads on designated music videos.
Two other key features were designed with mobile users in mind.
One was [INAUDIBLE] take it offline so it can play even when you're in a plane or in a metro, and the connectivity is weak or there's no connectivity.
The second is, a lot of times people are playing the music video and also doing other things on the device.
So we wanted to be able to do that.
Which is what background allows you to do.
Youtube is seeking feedback on what people want in a paid service.
But that's only part of the equation.
We have deals signed with majors and Indie labels, hundreds of them across all over the world.
But music streaming has hit a sour note with some artists.
Taylor Swift recently pulled all her songs off of Spotify, when she released her latest album.
In an interview with Time, she said, streaming music, quote, has been shrinking the numbers of paid album sales.
Streaming is here to stay.
And it's up to artists and labels to figure out how they can fit into that new feature.
And that's not lost on Taylor Swift or YouTube, where her latest video has been viewed over 270 million times.
