My brain is a sieve! I remembered that I HAD submitted some music a while ago, but most of it was just arrangements and because of that, I'd eliminated it from the "submitted, but rejected" category. Anyway, there WAS a piece in there that I'd used a text from a piece that that publisher had published and I sent my own setting to them because of their text. Turns out that the text was public domain, and they had said they would "keep it around in case they found a spot for it." Well, they kept it well over the usual 12 week turnaround time, so I emailed the editor and asked them to please make a decision. They did: Rejection #1. It was actually a very nice rejection, to be sure, but still a rejection. But it didn't kill me.

TGFM.
