Facebook messenger now allows you to share your Spotify songs and playlists. Spotify enabled this feature recently and no need of any updates to Facebook messenger to use this feature. It has integrated to the app directly.
TechCrunch stated :
Inside the Messenger “More” section in chat threads, all iOS and Android users will now find a Spotify option. Tap it, and they’ll be shuttled into Spotify’s app where they can “Search for something to share”. Once the select a song, artist, or playlist, they’lll be popped back to Messenger with the option to share the photo of the cover artwork. When a friend taps it that photo, they’ll be bounced over to Spotify to listen.
You can checkout this useful feature on your phone now.
