Scott...
While I sometimes use the Music Finder for requests I don't usually do, I find it cumbersome for my core songs because it takes a little time to check tempos, and in my case, key changes. Too much down time between songs.

I have found nothing faster than having my personal registrations on discs. On a "general audience" type of job I may have to use more than one disc, but they load fast.

All my Dinner hour registrations fit onto one disc. Regs for rest homes are on another.

On the jobs that require everything from Big Band to Rock, I interchange pretty quickly...but if a special set up is needed for a particular tune, I will put on a midi or MP3 and don't even try to give the impression I am playing live while I set up the special settings for the next song.

So far no complaints. What seems to matter most to the crowds is that there is ALWAYS something to dance to.
