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.
