Bom, nos testes que fiz, pelo menos no Feeder parece funcionar. =)
Not ideal, but what I do is to load all musics onto VLC, open the list view (Ctrl L on Linux), let the list fully load, sort by song name and check what appears repeated or that I don't want for other reasons. It also helps if the songs are metadata-rich, such as the ones bought from Bandcamp and ITunes (not Apple Music), so it's easier to differentiate them (given this community, I have no clue how/where from yours are). And lastly, there's a little plugin I found a while back that helps a bunch, vlc-delete, which adds the option to delete the currently playing file, and that, at least in the Linux version, benefits from motor memory since it can be executed with a quick succession of 2 Alt shortcuts.
The Reddit-inspired instances like the Mbin and Lemmy-based ones may be of interest for you. The Lemmy ones, from what I can tell, always hide the follower list, and the Mbin ones allow the user to choose between showing and not showing. Also, both seem to be able to connect to Twitter-like instances, though UI for that part in the Mbin ones is pretty barebones and the Lemmy ones mix them up.
Not familiar with LG's site so I don't have any links quickly available. But if it helps, and if you know the link or roughly where in the site the file was, maybe you could try checking Internet Archive, Archive Today, or, if the site has an Australian equivalent, the Australian Web Archive / Trove? Don't know other page-archiving alternatives, but if you do, I would also suggest checking on them.
So untrustworthy company is even more centralizing now?
