You can filter playlists like this:
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.
