LastGraph is now closed.
Thank you all so much for using LastGraph for these past seven years - it's been great, and I'm glad so many of you have made so many lovely graphs. I only hope that I can make one of my future visualisations this popular and long-lasting.
Why is it closed?
The last.fm API has stopped returning data and now just returns errors, and without it the website will no longer function.
Will it ever come back?
Perhaps if the API is ever fixed, but it's also probably just time that it was retired; people have moved on from last.fm.
What about using Spotify/Rdio/etc.?
If these services had an API to retrieve what music you'd played, and if I had free time, then perhaps - alas, neither is the case.
Can I get the code?
I've open-sourced the code on GitHub - if you're interested in how it worked, go take a look. I'm not able to help anyone out with running their own copy, though, as you'd need to port it off the last.fm API.
If you have further questions, you can always contact me, or just peruse my blog. A short history of the project can be found on its project page. Thanks to everyone who visited!
