My approach
Grab all my hip hop, RNB, dancehall.
Switch bpm range to less than 115 run analysis
Do the the same for dance, house
It’s my POP/TOP40 genre that I run into double/half-time difficulties, because my POP can go from low bpm to the high. Them ones I just fix as I come across.
I also lock them after analysis so they are excluded from my next full library analysis (which I do if analysis algorithm has been tweaked by the dev)
In a lil testing I did a while back Traktor appears to be the most accurate with BPM
Engine Prime/Engine DJ following the updated algorithm has the best downbeat detection
