I like Matt's idea of the standalone app but I'm intrigued by the possibilities of the Song Picker / spreadsheet combination.

Suppose you wanted to find all your songs that had used the same style and similar tempos.

You could use Song Picker to search your entire computer to get the list, then go to the spreadsheet and sort by Column C first, then by Column L. (you can't do multi searches in the Song Picker - at least to my knowledge).

Now I find all the songs using the (say) CHET.STY, sorted by tempo. I can quickly see which songs would "go together" perhaps for dancing.
