Return Array of All Artists for a Given Song

In ArtistSlideshow when I call xbmc.Player().getMusicInfoTag().getArtist() I get a string that may actually contain multiple artists. I'm parsing them on my end, but I wish I didn't have to try and keep up with all the ways the music scrapers split multiple artists. It would be great if for the next XBMC version (or earlier, I'd be totally OK with earlier) there was another call like xbmc.Player().getMusicInfoTag().getArtists() that would return an array of artists for a given song. Then I could just use that instead and quit trying to keep up with the scrapers manually.

Or is something like that already available and I just missed it?

Thanks.
