Reorder a Spotify playlist

Songs with matching musical keys land next to each other, so chord changes sound natural instead of jarring.

When the music is danceable, tempo matters most. When it's mellow, energy and mood lead the way.

We automatically look up each song's key, tempo, and vibe from public music databases. No account needed.

Step 1 / 3

Export a playlist from Spotify, Apple Music, Rekordbox, or write one by hand.

Step 2 / 3

Tempo, key, energy, and mood are pulled in automatically from public music databases.

Step 3 / 3

A smart algorithm finds the smoothest running order, then hands you back a new CSV.
