XSPF playlist metadata support (instead of only location)

Hi.
Would you please consider adding support for xspf playlists based on metadata instead of file location ?
It's one of the things which makes xspf the next generation playlist.
As it is now, xspf playlists in subsonic are only tracklists and not playlists.
Kind regards
