I don’t really agree with the linked post two following points in bold:
In this post, I think, replace the word ToC by Medium.
Indeed, I do have some Hybrid SACD but no longer own my SACD player.
So I can only fully inspect the CD layer and rely on what’s printed concerning the SACD layer.
Why should we either add everything or nothing?
We have always been able to add incomplete releases.
I would like to still be able to use the vague Hybrid SACD (SACD layer) when I don’t have too much time to spend on this or that SACD release or also when we don’t have that full understanding of the SACD structure.
I am beginning to understand the SACD structure of my own releases better but that is not the case when you start adding some Hybrid SACD, as a CD player user.
