Software is giving us ways of analysing our own listening habits that people never imagined a generation ago. Once you've tracked a lot of data, there's no end to the ways you can cut it — or present it. Recently it has seemed that I've come across a new way of visualising people's Last.fm data every week. I blogged a measure of my 'eclecticism' on my Last.fm profile a couple of weeks ago, but recently came across another way of measuring this. However, this has been a bumper week because Jadam Kahn has just catalogued several more visualisation tools over at the Rocketsurgeon blog.
I was going to write some reflections on these measures, and I still may, but in the meantime I recommend keeping an eye on Rocketsurgeon: the blog has only been going three weeks but has already built up a good head of steam.
