Our last.fm normaliser application recently celebrated its first birthday, and we're pretty pleased that not only has it lasted this long, but it still seems to be going strong. In that year, it has served up over a quarter of a million charts and now has over 215,000 albums in its cache.
It has been very interesting to compare usage with coverage - while most of our referrals come from last.fm itself, this article in Read Write Web, a link from Tom Coates and the launch of last.fm's directory of external applications all provided some welcome spikes in traffic.

After much head-scratching and a few hairy moments with the database this afternoon, we have updated the Last.fm Normaliser to use median track length values in its calculations, rather than the arithmetic mean values used previously.

After grumbling about the way last.fm calculates artist rankings, I realised that in the age of open data it shouldn't be too much hassle to knock together a little application to apply the normalisation calculation I discussed.
The application takes a last.fm username and recalculates the ranking based on an estimate of the amount of time you have spent listening to an artist, rather than the number of tracks played. It uses the excellent MusicBrainz web services to calculate an artist's average track length. Why not give it a whirl.
