The job I used to do at Spotify was to experiment with what could be made out of listening data, but the experiments that worked were then automated to run on appropriate schedules. These stopped working temporarily when my employee account was deactivated, but were revived, and some data-driven daily playlists are updating again. Currently no data updates are making it to everynoise.com, though, and all the big weekly jobs run on Fridays, so it remains to be seen what my ghosts there are still allowed to sing.
