This week Spotify began testing adding personalized song selections to its editor-curated playlists.
The new function will work with algorithmic song selections similarly to Discover Weekly or Release Radar playlists, helping tailor the editorial playlists to make them more curated to users based on personal taste.
It appears the Beast Mode, Chill Hits, Dance Party and Metal Ballads are all being used to test the function, among other genre, decade or mood playlists. It is only being tested with select users and will not be used on the most popular playlists, such as Today's Top Hits and RapCaviar.
"We are always testing new ways to create better listening experiences for more users, while also finding ways for users to discover more music," said a Spotify spokesperson in a statement.
