I have been an avid Spotify user for over a decade and as such, have an extensive music library saved, as well as quite a bit of history with the artists, songs, and playlists I've enjoyed. Unfortunately, I just discovered how great Last.fm could potentially be for music discovery and personal data analytics.
As of right now, I can't find a way through Last.fm forums or the Spotify Community to export my past decade long listening history from Spotify to Last.fm. I would love to not have to start from a blank slate if possible. I feel like it should be pretty simple, so would just like the added availability of exporting past listens to Last.fm specifically, though for broader use would be great if someone were to want access to that through other applications.

As of right now, Spotify doesn't allow users to see their full listening history, if you'd like that to change you should support this idea: https://community.spotify.com/t5/Live-Ideas/All-Platforms-Your-Library-Full-Listening-History/idi-p/...
