Play Count Tag

I love the details about my music files, How do you add the Play Count to MP3 Tag Files? Thanks

See the list of tag fields, esp. POPULARIMETER

Although you can fill it, I have not seen a single player that stores the play count in the files. The players I know save it in their own database.
And vice versa: no player that I know evaluates the field part and updates its internal play counter.
But maybe you know one.
