Music Listening Habits

In my various strolls around the internet today I came across this old visualisation of my music listening tastes:

By way of quick explanation the dots on the chart represent the chart position of the artists I listen to and the red or the green the size of the upwards or downwards movements of those artists over time (as I understand it).  In more detail, and as described by Martin Dittus, who computed the chart:

A simple visualization of music listening behavior over time: How frequently do you change your listening habits? How mainstream is your taste?

• Points represent chart positions
• Arcs represent chart movements

Point size corresponds to the combined reach of artists that inhabited this chart position.

Point color signifies chart entry- and exit-points: The green color component of a point corresponds to the number of times this chart position was an entry point for a rising artist, and the red color component the number of times this chart position was an exit point for a falling artist.

Arcs are directional and drawn clockwise: In the left half of a graph they point from bottom to top, in the right half from top to bottom.

Arc strength corresponds to the combined reach of artists that moved from the source to the target position.

Interesting stuff, and for those interested, here are some other chart arcs of staff members for Last.fm back in 2006.
