Spotify is testing a new Stories feature that will allow selected influencers to incorporate video elements into their public playlists. The first influencer to test the feature is makeup and fashion YouTube star Summer Mckeen, who currently has a social media fan base that includes 2.33 million YouTube subscribers. Mckeen is using the new feature to introduce a playlist of her all-time favorite songs, which she’s titled her “all time besties.” Like other Stories’ products found on social media apps, the Spotify version offers a similar experience that includes short video clips that users can tap on to advance to the next screen. There are also horizontal lines at the top that indicate how many screens still await them.
