You can filter playlists like this:

rating:0 AND (bitrate:>320 OR bitdepth:>=16)

Valid filters are: title, name, artist, album, albumartist, performer, composer, year, originalyear, track, disc, length, genre, samplerate, bitdepth, bitrate, filename, grouping, comment, rating.

The play- & Skipcount would be quite useful to have as well. Maybe I could add them in a pull request at some point.
