Apple Music is coming to Facebook Messenger

Apple will be introducing an Apple Music chat extension to Facebook Messenger, making it possible for people to bring the music streaming app into conversations with friends and family members and share music. Chat extensions are part of version 2.0 of Facebook’s Messenger platform. Spotify, perhaps the biggest competitor to Apple Music, is also introducing a chat extension. Within a Messenger conversation you can access Apple Music or Spotify by clicking the newly launched plus sign next to the text box and then finding the extension in the carousel.
