Follow-up...
I hope your experience isn't what mine will turn out to be, but this afternoon I get a message saying "We received this item back in stock, and it was shipped to you early today before we saw this email. You will receive a shipping confirmation email soon."
Wow, from "out of stock" to "back in stock" in just a few hours on a CD that I would venture to say they don't move more than two or three of in a year! I'll sit by my mailbox, but I don't have high hopes of listening to this particular CD anytime soon.
