Just say, "Alexa, play podcast Disaster Zone."
I don't know about you, but I have four different Amazon Echos in our home. In the office (great for spelling), bathroom for the morning news, kitchen for …. and bedroom, an Echo Show, so my wife Mary can read the lyrics to songs, and it is my alarm clock and plays music or the sound of thunder storms (I grew up in the Midwest falling asleep as a kid to the sound of thunder storms).
Now, you can fall asleep (well, maybe you should not use it for that) by asking your Amazon Echo device to "Play Podcast Disaster Zone" to hear the latest podcast in the series.
If you have not found the Disaster Zone Podcast, this link will take you to the current inventory of programs, with more being added each week.
