Mutliple Artists Sort Values

[GavinB]

Hi Folks

I know I can (and do) add multiple Artists by using the ; separator, and that I can do the same for the Artist Sort field. But do I need to include artists that don't need the sort specifying?

Examples...
Mark Ronson; Lily Allen gets Ronson, Mark; Allen, Lily

Mark Ronson; Kasabian - I could put Ronson, Mark; Kasabian but do I need the Kasabian part in the sort value.

What about multiple artists that don't need any sorting at all?
Oasis; Kasabian - I'd assume I wouldn't need anything in this case.

Thanks in advance.

Gavin
