Hi Nick,

As far as I can tell, bpmdj is a fancy playlist generator, intended for 
automatic (unattended) mixing, whereas mixxx is a live DJ mixer.  I 
think they serve different purposes, and I use mixxx because it 
provides the kind of direct control I want (and does it very well).

I haven't really used the playback features of bpmdj very much; I've 
only been using it for this BPM stuff because it has a nice graphical, 
interactive way to get very accurate BPM measurements.  The idea is, it 
shows you a square bitmap with one measure per column of pixels, and 
each pixel shows you the volume level (or some wavelet power thing) of 
that part of the song.  If your song has 4 beats per bar, you'll see 4 
horizontal lines in the graph when you have the BPM right, but the 
lines will be diagonal if the BPM is a bit off.  So you can see clearly 
whether the automatic BPM detection got it wrong, and you can adjust 
some course/fine sliders until the beat lines are perfectly horizontal.
