Dirble

//dirble.com/

Dirble.com is another radio station directory, made up of user-contributed content, and automatic streaming server polling.

It provides a JSON API, which as of v2 has a lot of unneeded meta information and internal ids. But it's actually nicer to scan, and contains even station homepages now.

The config option for a custom API key is perhaps redundant. Should streamtuner2 -D however reveal an error, you can however configure your own account there.
