I came across Last.fm normalised rankings recently, an interesting site that takes a look at your last.fm statistics and figures out which artists you've listened to for the most amount of time based on the average track lengths of songs. Perhaps unsurprisingly, I've spent 5,959 minutes listening to Stars of the Lid.

This kind of stuff really excites the info/data/web nerd in me. The more data in the world that's collected, and the more it's released and set free in standard formats, the more opportunities creative people have of finding ways to analyze and visualize it to help people make sense of things in their lives.

If you're a last.fm user, have a look at the Last.fm normalised rankings, it's pretty interesting.
