Back in 2014, a band called Vulfpack earned $20,000 with silence. In 2018, a random Bulgarian playlist might have scammed Spotify for millions. Now, “white noise podcasts” are apparently the hot new Spotify moneymaker.

The worst part of this story, however, is this correction:

Correction August 18th 10:25AM ET: An earlier version of this story said white noise podcasters could make $18,000 per year. It’s actually $18,000 per month. We regret the error.

$18,000 a year would be a nice little side hustle. $18,000 a month is a heck of a nice job if you can get it.
