let's say, hypothetically, I wanted to import my whole last.fm history (16 years) into ListenBrainz... can I even do that?

I tried the CSV import but, unsurprisingly, it did not want to import a 65MB file. I'd be fine running a script because idk if I trust that this import status on their website will work with my whole history

@eramdam Are you doing ListenBrainz also or instead of Last.fm? I'd not heard of it, is it worth the effort of transferring my scrobbles back to 2005?
