Facebook on Thursday announced Music Stories, a feature in its iPhone app that lets users post links to music they like with comments. Clicking the link will launch a 30-second preview of the music, which is streamed from either Apple Music or Spotify. Listeners then can purchase the music from the service or save it to their account there. Facebook plans to add other streaming services to the feature. There was no word on whether it will offer Music Stories in its Android or Windows Phone apps.by 208headlines
