Spotify's new playlist tool allows you to adjust multiple parameters, or match tempo and key, to blend tracks smoothly.

This is the latest feature from Spotify that gives users more control over their listening habits. Over the past few months, Spotify has launched the ability to customize genres for their Discover Weekly playlists, and customize their queues with shuffle and sleep timer options. Spotify's AI-powered DJ also now takes song requests.

You can be your own DJ. Spotify's latest feature is Mix, and, as the name implies, it lets you mix your playlists with transitions you choose.
