I can entirely understand that, and kind of agree. We have more data that anyone could know what to do with, but we should be doing more, I'd certainly like us to be.

To try and explain the apparent lack of activity; the last couple of years have had a lot of sorting-house, changes in product (moving away from on-demand, charging for some services, etc) and some technical "house keeping". Last.fm has been around for ~8 years, that is a long time and comes with a lot of technical debt, it can slow you down.

PS: One of my favourite things about Last.fm is our approach to openness of data, our API makes it totally possible for hypem (who are awesome, especially Anthony) to use your scrobbling data, even the recommendations we generate for you, on hypem.

We believe that if the data is visible on the website then there should probably be an API for it, because if there isn't, then someone will have to scrape it anyway.
