I was on The Deprogram!

The Deprogram is a podcast run by the YouTubers Hakim, Yugopnik and Second Thought (aka JT) that talks about socialist theory, with jokes.

Hopefully I got the <audio> element above correct. Your browser should prefer Opus, then Vorbis, and finally fall back on MP3. In Firefox seeking in MP3 doesn't seem to work, while both Opus and Vorbis work fine. This is because unlike MP3, Opus and Vorbis use the Ogg container which works fine in this case despite its many problems.
