Radio Paradise

Is there anyway to get Radio Paradise (https://radioparadise.com/home) streams to play though Plexamp Headless? I am currently using LMS (Logitech Media Server) and the only 2 things holding me back from transitioning my in home listening to Plexamp on the Pi is the lack of Radio Paradise integration and a client screensaver feature? Is this possible now or something that could be considered in the future?

Blunt answer, NO.

PlexAmp is used as a client for audio using Plex Media Server. PMS currently does not have any mechanisms for external audio streaming. It has a commercial relationship with Tidal and has Tidal integration but nothing else at the moment. There is no internet radio station integration.
