I was scratching my head quite hard after waiting a day and the status did not budge at all. I decided to translate my last.fm scrobbles using a JSON exporter to a libre.fm CSV: jq -r '.scrobbles[] | [ (.date | (. / 1000)), .artist, .track, .album ] | @csv'
Perhaps I should have been more patient, but there reports of scrobbling failing to work, most likely due to last.fm changes. I am still waiting for the libre.fm imports to actually show up on my profile.
