Facebook introduces a new music feature to share nicknamed 'Stories Music'

Facebook has made it easier to share music, introducing a new message format amid the boom of flows. Nicknamed "Music Stories", the new format allows people to hear a 30-second preview of the shared song (or disk), while in Facebook.

A person who listens to a song in a streaming site would click "share" and then "copy". He or she then paste it on Facebook, adding the comment, if desired, and friends to see the post with options to listen to the song.

"We hope to make this the best experience, artists share more, share and engage more friends, and music will become a better part of the Facebook experience overall," Michael Cerda, product manager at Facebook - second website more popular in the world after Google - wrote in a blog.

Music stories marks the latest effort to expand forms of content on Facebook, which allows its more than 1.5 million users exchange messages, photos and videos. Apple and Google have both paid platforms released for streaming music, which allows unlimited a la carte selection of songs online.

Spotify, despite criticism from some artists, maintains a free advertising-supported layer, which means that Facebook users can listen to songs recommended by friends without paying.

Facebook, which reported stronger than expected earnings Wednesday, winning the majority of its revenue from advertising and, unlike other Internet giants, has focused on staying free for users.

Streaming has been growing rapidly, with industry revenues in the US increased 23% in the first half of 2015 compared with the previous year, according to the Recording Industry Association of America.

Spotify, started in Sweden, remains by far the largest streaming site. It says it has 75 million active users, of which 20 million paid subscriptions.
