Streamtuner2 is based on concepts and the UI of the original [streamtuner by Jean-Yves Lefort.

  *  The original was implemented in C with Gtk2 bindings, but already had the ability to harbour Python-based plugins.¹
  * It was much faster and less memory-hungry.
  * Keeping the parsing up to date with the ever-changing directory services however wasn't feasible.
  * It **still works** with the **Xiph**/ICEcast directory, btw. Because their `yp.xml` didn't change so far.

The ST2 Google plugin was based on parsing rules from ST1. (It has been retired meanwhile though.)

¹ IIRC, I've originally even tried to reuse the original Python plugins. But that didn't pan out.
