rien333 [1] filed a deletion request for bandcamp-dl [2]: A package with the exact same name (i.e. https://github.com/iheanyi/bandcamp-dl) and the same functionality (though it includes more fairly essential features) is still see seeing active maintenance, while this has been unmaintained for a couple of years now.
