Sites for downloading high quality music files

I am making a script that can download high quality music files, currently from free-mp3-download.net and slavart.gamesdrive.net. Are there any others? I could look into torrenting things automatically and maybe looking into Lidarr? Not 100% on how that works but any ideas on what else I could add or links to other places I can download high quality music files lmk.

Thanks in advance.

EDIT: I've found Jackett that could be promising, but still open to other ideas/sites.
EDIT: Thank you all for your responses.
