Help with Music button

Can any of you clever programming types help me?

I have a large directory of music. Each sub-directory is labeled with the Artist and the Title of the album, and obviously, each sub directory contains the music.

I want to create a button that will allow me to type in the name of the artist and find all the albums (sub-directories) labelled with that name. (I DO NOT want to return any songs in the found sub-folders)

All my many attempts to construct the button have failed because the button returns the folders and the songs inside them.

If you go to the music directory, push * and type the artist name, the filter bar should do the rest.

(If you don't see anything, type a * after the name. Whether or not you need it depends on the Partial Matching setting in Preferences.)

Magic. Many thanks Leo.
