I'm trying to figure out which fields to put different categories in - - specifically between "Collections" and "Sources".  Since the Collections field has more filtering options (include or exclude...) it seems like I should just put all categories there and not use the Source field at all.  But I'm wondering if there is a reason I'm not getting that I should put some categories under  Sources?

The categories I'm working with now are vocal, choral, satb, ttbb, a capella,  etc.

Thanks to anyone who can offer me some insight on this.
