Music - Visualized (or is that Audibalized?)

Furia puts together a visualization of pretty much every style of music there is (and a huge catalogue of the artists in that style of music).  You can click on a genre to hear a typical example, or click on the associated arrow to see the artists - and hear them.
I wonder what one calls this - an Audibalization? An Audi-visualization? Regardless, its pretty cool!
