I draw the line with Spotify's own content policy (https://newsroom.spotify.com/2018-05-10/spotify-announces-ne...) that states:

"However, we do not tolerate hate content on Spotify – content that expressly and principally promotes, advocates, or incites hatred or violence against a group or individual based on characteristics, including, race, religion, gender identity, sex, ethnicity, nationality, sexual orientation, veteran status, or disability."

Given that Jones own InfoWars podcast is already banned on the platform, I think where the line is, is pretty clear.

Wouldn’t a large percentage of rap songs, e.g. eninem fail this test. You can find some very hateful lyrics

A person is not content. Alex Jones is not InfoWars podcast. I haven't listened to the podcast in question, because why would I, but if you think that it does violate these rules, you should prove it.
