This question is asking where they can buy a specific recording:
Is this on topic? I would think that this information can go out of date pretty easily as sites come on and offline and licensing for the recording changes.
TL;DR - No, they are off topic.
Being that the primary purpose of Stack Exchange sites is to create a long-term searchable repository of knowledge, and that answer to this kind of question will, of necessity, be ephemeral in nature, I would have to conclude that we should make all such questions off-topic.

Related & not enough to split to a new meta question, perhaps.
It's not so much a "Where can I find?" as a "Does it even exist?"
I'd call up/downvotes to this answer sufficient for a quick consensus on whether it belongs here or not, after considering the other answers here.
Personally, I have no firm opinion, I'd quite easily go with the flow.
