MyOggRadio

MyOggRadio is an open source internet radio directory project. Since it provides its station list as JSON it's very well supported.

Because the directory is currently still rather small, streamtuner2 provides the option to share radion station links. Use the Station ▸ Extensions ▸ Share... menu entry to upload the currently selected radio (from your favourite bookmarks).

The personal section is empty per default. You need to specify an user account in the settings dialog, and actually bookmark stations in MyOggRadio web site. Shared entries are not automatically in the MOR favorite list.

There's also JMyOggRadioPlayer as specific frontend and player for MyOggRadio.

Channel options.

Login settings: If you want to upload station infos to MyOggRadio, you need an account there. Registration is free and doesn't require personal information nor email address. Specify username and password separated with a : colon in this field.
stream URL format: When uploading stations, the streaming URL can be converted into RAW format. You can however leave it as .PLS link file.
