I recently tried shortwave (flatpak) and it works pretty well. Let's you search for public streams, and if the radio stream includes song data, it even auto records individual tracks for you if you want. Pretty minimalist and functional
Ehh honestly I just use MPV and store radio stations as m3u files:

If it doesn't say the year it means Nov 10 this year. The page you linked shows last release was 2 weeks ago for me.
I can't compare because I've never used radiotray but goodvibes and shortwave are both quite minimalist.
Well, it might be totally stupid advice, but can't plain simple VLC fit in?
When I open your link for radiotray-ng, it says, "ebruck released this 2 weeks ago." You'll also notice if you go to the Releases page, it doesn't show the year for the current year, but does for past years.

Simple terminal radio, lots of stations to choose from, customizable.
GNU radio: hard mode enabled.
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
