For some albums there appears to be more than one disc?
In the first image the tracks are in order and so play in order.
But in the second image they are not. I suppose this would be OK as in most albums order is not absolutely necessary but in classical and many other situations (e.g. concept albums) order is everything, or nothing. Making a playlist for the album is no good as the tracks can not be reordered except by painstaking cut/copy/paste.
Any fix? Any ideas?
