Once upon a time, you could download old episodes of This American Life by grabbing MP3 file locations from the M3U files posted on their website. The MP3 files lived here:

http://audio.wbez.org/tal/SHOWNUMBER.mp3

But that stopped working.

These days, though you can still listen to TAL archives, downloading them has become a bit trickier because the shows are hidden behind a flash player. But, that flash player is still pointing to an actual downloadable MP3, and Christopher Soghoian has figured out where they live:

http://audio.thisamericanlife.org/jomamashouse/ismymamashouse/SHOWNUMBER.mp3

Come on… that directory structure is pretty hilarious.

Replace SHOWNUMBER with the episode number (338 for example), and you’re good to go.

If you download and enjoy This American Life, you really should donate.
