Well I haven’t got around to writing any “Top X of 2009″ posts so in honour of the last day of 2009 here are some visuals of my last.fm stats over the past year.
Tube Tags for 2009

This visualisation shows the changes in my listening over the past 12 months. Each coloured line represents a tag, with key artists listed underneath. The white circles appear with tag names whenever there’s an increase in listening for that tag, so you can quickly read the bias for that month. (via the last.fm playground)
LastGraph Timeline

A ginormously sweet oceanesque wave of data! Make your own at LastGraph. I enjoy viewing the spikes in artists directly after a new album is released or I seem them live. Good times.
2009 was dandy year for new tunes. Hopefully 2010 can compete.
