I agree that the comma is better than the slash here, as it is somehow 
softer. I think you and Andrew are on the right track when you use 
"Symphonies No. 1, No. 2 / Whatever Overture".

I want to repeat that I think MultipleTitleStyle is irrelevant for 
ordinary classical releases, except for the "space, slash, space" thing. 
IMO the reference from CSG should be dropped, as it encourages ugliness.

And I reiterate my point: I think the style of the original title should 
be followed as much possible.
