SurfMusic

SurfMusic is a user-collection of internet radios. It's grouped by genres, or locations / countries.

It's both pretty large and rather quick to extract listings from. And it mostly includes station homepage links.

The MusicTV and NewsTV sections also return results, but those are mostly web-based video stations. Some of them are outdated links even.

Channel options.

Language: There's an English and a German variant of this radio directory. Genres are also localized. Restart streamtuner2 after switching the Language option. Then use Channel ▸ Reload category tree.
