There are a few ways to handle this.
Make the "Artist" field into a list field. In order to do this you'll have to create an expression field, lets call this field "Artist (List)". Use the follow expression
[Artist]&datatype=[list]
Now when filling in the "Artist" field use ";" to seperate the artists
Example 1:
Ry Cooder & V.M. Bhatt;Ry Cooder;V.M. Bhatt
"Artist: List" will look like
Ry Cooder & V.M. Bhatt
Ry Cooder
V.M. Bhatt
Example 2:
Ry Cooder;V.M. Bhatt
"Artist: List" will look like
Ry Cooder
V.M. Bhatt
Another way to do this is to create 2 additional fields, one a list field and the other an expression field. We'll call them "Artist: Additional" and "Artist: List". "Artist: List" will be an expression field and will use the following expression
[Artist];[Artist: Additional]&datatype=[list]
You would use the fields like this
Artist = Ry Cooder & V.M. Bhatt
Artist: Additional = Ry Cooder;V.M. Bhatt
The result is the same as example 1.
