Ouch. Hope all is OK.

Alternatively, with many sort algorythms, things with the same sort
key stay in the original order when sorted. In this case, do a sort
on the least significant key first, then work up to the most
important. In your case, sort on Title first, then Artist.
I don't know whether this will work with the particular sort used by
Blitz, but it won't take too long to try it out.
