I plan every job and put together a specific MFD file for that audience. The list, however, is only a basic guideline, and like most folks here, I stray from the list to satisfy the audience. If a certain era's of music fills the dance floor, I'll pretty much stick with it through most of the gig. Later, I'll put together a specific MFD for that audience--it just makes life a bit easier the next time you play for them. You must be flexible and respond to the audience at all times--they're paying the bill.
