Today Spotify is announcing a new feature that works... inside Facebook Messenger. The online music streaming service now lets you build group playlists in Facebook's messaging app.
It works very easily. When you are inside a group chat in Messenger, tap on the "+" in the lower left corner, choose Spotify, then create a playlist. From that point on, you as well as your friends who are participating in that group chat can add songs to the playlist. Interestingly, even people who aren't on Spotify can part-take in the playlist creation, adding songs too.
This is a very straightforward way to share music with your acquaintances, and it can be very useful in certain situations such as road trips or parties, when many people want to contribute some of their music tastes.
