Currently on ListenBrainz you can connect your account to various music services to import your recent music listening history.
However only the LastFM importer currently allows you to import your entire history.

Most music services will have a way for users to download their listening history files, at least where GDPR applies.
These files come in a variety of formats, so a generic importer system should be created to handle generic logic, while specific file formats and schemas should be implemented separately for each service.
