YouTube officially joins the market of having customers pay for their service. The world's most popular website added a new feature for listening, watching and downloading songs with videos. To get this service you have to pay 7.99$ per month.

This service is named as "YouTube Music Key" which would be ad-free. This service can be get online as well as offline by giving certain amount of money.

This sort of service also provides by the websites like Spotify, Rdio and Beats Music. According to BBC, YouTube's this service is not aiming for computers at the moment. Android operating system users will get this service before others. Afterwards this service will be available to Apple's iPhone and tablets. But at this time this remains only on the smartphones.

According to techcrunch.com, YouTube spokesperson Matt McLernon says. "Overall, we rely on the information that we get from our partners, or from the video uploader," He added "So there are very specific cases like members of the music community, say a label or a publisher, where it's very clear that it's music, but the thing that makes YouTube so unique in the music space is, not only is there the traditional music side that everyone knows and loves, but with 300 hours of music and video coming to YouTube every minute, and much of that being music, there's this whole spectrum of what people call music, or consider music, or share as music."

Though YouTube describes itself as "the biggest music service on the planet", but experts has enough doubt about its success. "If you are someone who only listens to Spotify and doesn't listen to YouTube, this won't be a good enough reason to switch," said James McQuivey who is principal analyst at the Forrester Research consultancy.

At first YouTube's "Music Key" service will be sent to certain users as a special invitation. Whoever get this invitation which is a developer edition will get a chance to use it free for six months.
