I don't know. I give the MB 200 each year to my wedding clients at our first consult in my packet to help with selecting must plays and no-plays, but I never look at it myself or refer to it during an event.
The only thing I have ever looked at during an event for ideas are lists provided by the client.
Way I see it, if you have "run dry" for a selection in a given set, it's time to transition to a different set.
There are really only two scenarios:
a) The floor is hopping - if you got it hopping and have
kept it hopping - then chances are you know what
will continue to keep it hopping until YOU
decide it's time to change it up. Before I'd take a chance on destroying a vibe or a killer set with a gamble from a list, I'd simply transition out into another set that I know will be just as well received.
b) The floor is dead or only mediocre - If it's dead or mediocre, ANY song you play - from a list or not is a shot in the dark and you should only rely at that point on what your experience tells you
tends to work for similar event types/demographics, etc. And no list is going to help you with those considerations.
They may work for some, but for me, lists like this are only of value or help if you need or want to use them to plan certain selections or get ideas
ahead of time, but in the heat of the moment - while mixing it up - as a tool to "save the day" or magically keep a set going or get one started I don't know. I just can't see it happening. But then I'm notoriously bad at multi-tasking....
At the end of the day there is no universal answer. It all depends on how you work and how your brain works. Lists will be tools for some, a crutch for others, and completely useless for the rest. Since all value is attributed, a thing is only as valuable as any individual deems it to be.
