Spotify is rolling out a new feature that’s meant to make transitions in between tracks even smoother. If you’ll recall, the streaming service released the ability to create customized transitions within playlists in August last year. It gave people a way to create uninterrupted progressions and eliminate awkward silences between songs. Now, Premium users will be able to make sure the songs in their playlists flow seamlessly even further by reordering tracks based on their keys and BPM or beats per minute.

The new feature can rearrange playlists with one tap. All paying users have to do is tap Mix on one of their playlists and then tap the Edit button. From there, they can scroll down to find the Smart Reorder option. Tapping Smart Reorder will automatically rearrange songs according to their keys and BPM without users having to do anything else. They just have to click Save so that the change to their playlist takes effect.

Spotify says users have streamed over 220 hours of their mixed playlists since it introduced custom transitions last year. It also listed some of the most popular ones on the platform, including The Weeknd’s Wake Me Up transitioning into After Hours and Flo Rida’s Low into Rihann’s S&M.
