Spotify is deploying a feature that lets you tell him to ignore music in certain playlists when he decides what type of music you like. The feature is called Exclude from your taste profile, and the company promotes it as a way to prevent your recommendations from being flooded with “songs and artists that don’t fit” with your general listening habits.

It’s easy to imagine different scenarios where this capability could be useful. Your sleep playlist may end up getting a lot of listening time, but it may not contain the kind of music or sounds you want to listen to while you’re awake. It’s a similar story with work playlists, which can be very different from your off-the-clock music tastes. (One of my co-workers commented that their lo-fi beats playlists “killed” their weekly discovery when we discussed this feature.)

Spotify also says it’ll come in handy if you have kids – the feature lets you make a playlist of their music easily accessible without telling the algorithm you want loads of Kidz Bop or Pinkfong in your daily mix.

The company says you can exclude playlists using its iOS, Android, and desktop apps as well as the web player. To do this, select the playlist, tap the three-dot button, and then tap the “Exclude from your flavor profile” button. You may not have the feature right away, as Spotify says it just rolled out today.

This isn’t the first time Spotify has given users control over what does and doesn’t affect their algorithmic recommendations. like you enable a private session, anything you listen to won’t color your Made For You playlists. While you could technically do that every time you want to listen to work or kids music, it would be a lot more annoying than just setting up specific playlists so as not to affect your recommendations.
