I'm not going to download files, then open them. sorry.
It's likely I run across enough 'electronic germs', without [figuratively] sharing needles/taking electo-transfusion of programs & scripts, etc...
If I had just the right NSA email addresses, I could probably ask them (and they would know, *they* know everything -- but next to nothing, at the same time) but I'm not in the right info loops.
I do remember the WBAP station identifier "jingle", little ditty-like, short soundtrack from the sixties though, and can reproduce reasonable facsimile of it, in my mind's ear (so to speak).
I wonder...do they still use them, or at least bring them out every once and a while, like, to introduce particular segments?
The links were for live radio streams from the stations in question that you would play in a media player, like Windows Media Player, Clementine, or VLC. They weren't files to open up.
What is the subject matter of the radio ads?
The subject matter was an interpretation of Bergoglio's environmental encyclical. Certain quotes.
