Then as it is unclear how to easily proceed with low-level curl/requests to the download of the given sound tracks, `media_files_extractor.py` use Selenium to leverage previous step retrieved metadata to download one-by-one all the sound tracks to Selenium default downloads folder, which is on Linux `~/Downloads/`.
The current issue with this repository is the stability, as at some point the algorithm stops being able to retrieve metadata or download correctly, cf https://gitea.lemnoslife.com/Benjamin_Loison/YouTube_Audio_library_extractor/issues/10.
