The AND-window sets both the parameter statements and the query statements. From it the user can directly enter the EDIT-MENU or return to the OR-WINDOW.

By sorting the songs/dances for the various numerical parameters, values can be found that allow the selection of songs/dances e.g. in the following intervals:
Minimum : the dance(s) with the lowest value
Small   : Minimum <= x.value <= Small allows about 25% of dances
Intermediate: allows about 50% of dances
large : about 75%
Maximum: the dance(s) with the highest value.
It is debatable what to do if an inbetween value returns the same value as one of its siblings, but as long as the user is shown the resulting amount of songs, this can be defered to a later data.

For sortable non numerical data the developer should be allowed to supply a function which limits the amount of choices the user has to wade through (akin to the above.) Otherwise all possible options should be shown.

Minimum and maximum values should be limited to sane choices. Do not display choices that will not allow dances/songs.

If name editing is not allowed, the interface above can be executed with the existing 'ui' commands.
