Setlist Momentum measures how "hot" a song is right now by looking at performances over the past 2 years. Recent performances count more heavily than older ones, so a song played last week contributes more to momentum than one played a year ago.

Momentum is scored 0 – 100, where 100 would mean a song was played at every show. However, due to deep setlist rotation, even the most frequently played songs typically score in the 10 - 20 range. Higher scores indicate more frequent appearances, while lower scores suggest occasional or rare plays.

The trend icon shows whether momentum is heating up (↑), cooling down (↓), or staying stable (−) by comparing performance frequency in the recent half of the window versus the older half.
