Songbird needs to follow multiple artist separation ID3v2.3 standard

I need proper ID3v2.3 artist separation for Songbird. You should really implement this, for it's described in the ID3 standard. Multiple artists are to be separated by a slash (/).
What would change:

Old behavior:
Artist tag "David Guetta/Cozi" is displayed inside the library as "David Guetta/Cozi". That leads to multiple entries that don't help the user.

New behavior:
Artist tag "David Guetta/Cozi" is displayed as 2 separate library entries, namely "David Guetta" and "Cozi", who both point to all of the songs the respective artist is involved in.

That's the way it should be. Following standards and making the library better.
There should be a hard-coded work-around for AC/DC though.
