I was expanding on the explanation; specifically, explaining why it fell through to a seemingly-unrelated handler.  Amazon seems to think that what they've done is right, although they didn't always do this.  At some point in the past, it would return an error saying that she couldn't understand what you wanted.  Now it falls through to the last intent in the model on a no-match.

For anyone wondering why she responds by playing recently added songs when you didn't ask for it, that's why.
