A mashup is a song created by blending two or more other songs. The more complex a mashup gets, the harder it is to distinguish the parts that are being used to create what you’re hearing.

This visualisation of the song “Definitive Daft Punk” by Cameron Adams dissects a mashup in realtime to show you how each of the 23 parts contributes to the greater whole.

A really cool usage of Javascript, HTML5, and CSS3 to show how a mashup of 23 Daft Punk songs are layered and made: http://daftpunk.themaninblue.com/
