What would you need an addon for? If you enable the clipboard monitor, jdownloader automatically adds all downloads it finds from any link you copy.

Edit: If you don’t like the clipboard monitoring you can also use the Open With addon to explicitly add links.

If no person does anything nothing changes.

Of course your own choices in isolation don’t change much. But that’s like saying voting doesn’t do anything because a single vote doesn’t matter. We all can make choices that add up through all of society.

If musicbrainz has an acoustic fingerprint for the songs it doesn’t need metadata. Picard is more or less the GUI version of beets.
