I developed Deezerart, a Picard plugin to fetch cover arts from Deezer, a music streaming platform. Deezer provides free APIs with a reasonable time limit that are perfect for such a plugin.
Deezerart has been tested from Python 3.5 to Python 3.8, to maximize compatibility, although I only tested it in Picard 2.4 since that’s the version my distro ships.
I tried to use all the cover-art-related APIs in Picard so that every menu entry and error message appears in the right place, well integrated with the overall application.
It is my intention to create a pull request to add my plugin to the official third party Picard plugins, should you wave the green flag.
I hope you’ll enjoy Deezerart!
