Very good. Few suggestions:
-Remove the high bitrate option if not used

• You can add 2 buttons to go to the links. See: https://volumio.github.io/docs/Plugin_System/UI_Configuration_Pages.html

Not good for merging, it fails to start.
How to replicate:

• Install the plugin (on a new system)
• Go to plugin settings an enable it
• It will fail the start and crash the system
