Shortwave, the successor of Gradio, had it first beta release over the weekend. This is a GTK Internet radio player written in Rust, which uses radio-browser.info as its radio stations database.
Background: The Gradio developer wanted to rewrite Gradio using Rust, but later started a completely new project called Shortwave. There will be no major Gradio releases, but don't worry as Shortwave will include all important Gradio features and more.
Using Shortwave you can search for Internet radio stations, listen to them, automatically record songs, and even stream to Google Cast-enabled (Chromecast) devices.
