Spotify tests Tastebuds, a function that gives users music tips based on friends with a similar taste. This is reported by software researcher Jane Manchun Wong on Twitter.
On a found page, which is otherwise useless for users, the new feature is described as a way "to discover music through friends whose tastes you trust". Through Tastebuds people can see from each other which songs they have listened to the most.
Recommended by friends could be added by users to their own library. It is not known if and when the function will be added to the public version of Spotify. For the time being it seems to be a prototype that is being tested internally.
Tastebuds could make Spotify a more social music service. At this moment you can see what friends are listening to at the moment. Public playlists from others can also be seen and followed and music can be shared on social media.
Furthermore, Spotify offers hardly any social options, although the service has experimented with this more often in the past. For example, a Friends Weekly playlist was once found, which would bundle together much-heard music from friends. This option never ended up in the final version of Spotify.
