Thanks frankz! That's it.
FWIW, anyone looking for a BPM analyzer, there's no reason to purchase MixMeister at all, I should have started with
http://www.abyssmedia.com/bpmcounter/ which is free. I think it's a better interface, and it has the option to write or not write to the tags. MixMeister will always write to the files after processing, there's no option to turn it off that I can see.
Plus BPM Counter lets you set the number of decimal places, whereas MixMeister is hard-coded to 2 extra decimals: "XXX.XX".
The only downside to BPM Counter is it doesn't support drag-n-drop the way MixMeister does, you can only add files by navigating to a folder.
