Spotify Launches Smart Reorder: Auto-Arranging Playlists by BPM and Key

Spotify is rolling out another artificial intelligence feature aimed at improving how listeners experience their playlists. The new Smart Reorder function automatically reorganizes tracks based on musical properties like beats per minute and harmonic key, letting Premium subscribers reshape their collections with minimal effort.

Users can access the feature by opening a playlist, tapping Mix, then selecting Edit. From there, scrolling down reveals the Smart Reorder option. One tap triggers the algorithm to rearrange songs according to their keys and BPM. Saving locks in the changes. No manual tweaking required.

This represents the latest chapter in Spotify's push to make playlist curation smoother. Last year, the platform introduced custom transitions between tracks for paying subscribers—a feature that let listeners engineer seamless musical bridges from one song to the next. Since then, users have streamed over 220 hours of these mixed playlists.

Some listener-created transitions have emerged as particularly popular combinations. The Weeknd's "Wake Me Up" flowing into "After Hours" tops the list. Flo Rida's "Low" paired with Rihanna's "S&M" draws consistent plays, as do Sean Paul's "No Lie" transitioning to Coldplay's "Adventure of a Lifetime," and Kendrick Lamar's "euphoria" connecting to Skepta and Playboi Carti's "TOXIC."

Before Smart Reorder, listeners could check each track's BPM and key after tapping Mix, then manually reorder songs to create smooth transitions. The new automation skips that step entirely, handling the heavy lifting in seconds.

Spotify also unveiled a Mixed By hub featuring collaborative playlists from artists and curators including John Summit, Becky G, Normani, Beele, Mike Shinoda and Joe Hahn of Linkin Park, Odeal, Groovy Room, and monte booker. The hub serves as a reference point for subscribers exploring the reordering tool and discovering how others approach transitions.

Mixed playlists remain shareable with friends. The transition editor and Smart Reorder both work on collaborative playlists, meaning groups of listeners can collectively refine shared collections. Spotify also allows users to design custom cover art for their mixed playlists using the platform's built-in image editor, a tool that debuted in 2024.
