Two songs at 95 BPM can do opposite jobs: one is a lover's rock groove that melts the room, the other a peak-time anthem that detonates it. Tempo measures speed; energy measures impact — drum density, bass weight, vocal aggression, arrangement. DJs who sort by BPM alone keep reaching for "same-speed" songs that kill their own momentum. The fix is a second number.
| Band | Feel | Dancehall/reggae/soca examples |
|---|---|---|
| 1–3 | Chill / settle | Lover's rock, slow jams, R&B blends |
| 4–5 | Groove / standard | Standard dancehall, conscious reggae, mid R&B |
| 6–7 | Dance / club | Club dancehall, hype hip-hop, peak-time build |
| 8–9 | Peak / road | Carnival soca, power soca, road march, wheel-up anthems |
Score it once, write it into a tag Serato displays (Comment works), and the number travels with the track forever.
Open (first hour): 4–5. Nobody dances to a 9 in an empty room — they just notice the room is empty. Build: 6–7 as bodies arrive, with 5s as breathers. Peak: 8–9 in waves — two or three songs up, one down a notch, back up; a flat ceiling of 9s numbs the floor within twenty minutes. Land: step down on purpose — the last thirty minutes decide what people remember. The most common rookie kill: two drops back-to-back at 11pm, floor peaks early, nothing left for 1am.
Hand-scoring a library is honest work that nobody finishes. RiddimDJ Pro's Energy Analyzer listens to the audio itself and scores every track 1–9 — analyzing the actual bars, not the metadata — then writes the score to a Serato-visible tag, color-banded so you can plan transitions at a glance. Whole folders in one pass; files never modified until you save. Combined with key ordering (the Camelot guide), your gig crate becomes: right riddims, right keys, right energy curve — before you leave the house.
