YouTube Music Key beta officially launches

The beta of YouTube's highly anticipated music streaming service has been released in selected countries.

YouTube's official streaming service, Music Key, is finally here. After multiple delays and squabbles with independent record labels the service can finally be accessed by those fortunate enough to get invited into the beta test.

For years YouTube has been the go to place for people looking to listen and watch the latest singles and music videos. Music Key makes this experience even better and more comprehensive with a huge number of new features.

The latest YouTube update for iOS and Android devices brought in a new Music tab that makes finding singles from your favourite artists easier than ever.

Don't get confused though, this is not Music Key. 

For now Music Key is only available in the US, Spain, Italy, Portugal, Finland and the UK, to those who are invited into the beta trial. How you get invited onto the beta is currently unclear but YouTube have said its giving out invites to their "biggest music fans first." 

Beta invitees will get to use the service for six months without charge, followed by a lifetime loyalty discount, meaning those select people will only be charged $8/£8/€8 when the full service officially launches.

When Music Key launches to the rest of the us we will have to pay $10/£10/€10. For that fee you will have access to both Google and YouTube streaming service completely advert-free.

Other significant features include the ability to listen to songs in the background on mobile devices, offline listening, as many playlists as you like and as stated above access to the Google Play Music library.

YouTube Music Key will go head-to-head with the market leader in online music streaming Spotify, and Apple's Beats streaming service which is rumoured to launch sometime in 2015.
