I was super into grabbing the stream database they are using. (For my own personal wifi radio)
This page has an interesting behavior when used without a session key: http://data.radio.garden/live.json It returns stations but with fake/warning data.
id "radio-afghanistan"
name "This app is fake"
website "http://rta.org.af/"
src "http://radio.garden/public/fake-app-warning.mp3"
I guess they don't intend on opening any of this up
