Artista feat. Artistb

[elemay]

I guess this is really just a matter of personal preference but i was wondering how you guys were handling a song by an artist featuring another artist.

I've seen all sorts of tagging out there.
My current way of doing it (which is not great) is by including the "featuring" artist in the title of the song.
e g. Money for nothing (feat. Sting)
By doing it this way i can't really search a song by the "featuring" artist.

I'm not sure it's worth retagging my whole library but I was wondering if some of you were actually using multiple ARTIST tags for such songs?

Thanks for the thoughts.
