Reading the energy curve

A setlist that reads well on paper can still die in the room. The energy curve, shown inside Smart Reorder's AI Setlist Analysis, plots your set so you can see its shape before you play it — your current order against the AI's suggested order and the target shape you asked for.

How the energy score is worked out

Every song gets a score from 1 to 10, based on BPM:

BPM	Score
70 or under	2
71–80	3
81–90	4
91–100	5
101–110	6
111–120	7
121–130	8
131–145	9
Over 145	10

A score of 7 or above shows as 🔥 high energy, 4–6 as 〜 medium, and under 4 as ❄️ low — you'll see these icons next to each song in the current-order and suggested-order columns.

A song needs a BPM for this to mean anything. Fill it in yourself, or use Auto Fetch Info in the song library to look it up — see building your song library.

What a good curve looks like

There is no single correct shape — it depends on the target you picked before running Smart Reorder:

🔥 Bang to Bang — energy stays high (7–10) throughout. Right for a festival slot or a room that wants nonstop dancing.
〜 Wave — open strong (8–10), settle into a varied groove in the middle (5–8, with room for a quieter moment or two), then build back to the highest energy song of the night for the close.
📈 Gradual Build — start mid-energy (5–6), save the biggest songs for later, energy climbing steadily to a peak in the final stretch.

A wedding dinner set intentionally sitting low throughout is correct, not broken — pick the shape that actually matches the gig.

What the warnings and improvements mean

Smart Reorder surfaces specific issues (⚠️) and things that would strengthen the set (✅) directly above the song comparison — these are generated for your actual set, not fixed rules, but they consistently come back to the same few patterns:

Same artist too close together. The AI tries to keep songs by the same artist at least 3 positions apart.
Too many slow songs in a row. More than two consecutive ballads will empty a dance floor.
A weak "second wind" moment. Roughly 60–65% through the set is where bands most often lose a crowd if the energy doesn't lift.
A soft opener or closer. The first song needs to grab attention immediately; the last needs to be the one people leave humming.

Fixing a set that drags

Look at the curve, not the list. The shape shows you the problem faster than reading song titles will.
Check your BPMs are filled in. A song with no BPM can throw the whole reading off.
Try a different Energy Shape. If Wave isn't landing, Bang to Bang or Gradual Build might suit the gig better — Smart Reorder lets you change shape and regenerate.
Use special instructions. If you know exactly what's wrong — "too many ballads after song 10" — say so directly rather than just regenerating and hoping.
