This isn't defined for plain TeX.

I disagree.  `@' should *always* be of category `other' for the user.
If she wants to change that she should explicitly change the catcode.
This is standard LaTeX practice.

Since LilyPond completely takes care of formatting pages, this isn't
really useful.  Think of LilyPond returning an `image' of a piece of
music which is accidentally in TeX format.  If you want something
between the systems, make LilyPond do that.  Otherwise use two or more
LilyPond snippets.
