This is what I use on my HD:
http://www.psrtutorial.com/Resources/Articles/organize.html While I like being able to have the Music Finder select the intro and starting variation and other features, in a live situation it is really too slow.
With the set up I use on the HD I can be playing one song and already have found my next song. When the ending of one song stops, I can immediately press the new song and start the new song with really no time in between if needed/desired.
