Stuck in my head

So for the past few days I've been driving to work listening to the same song, over and over: "Hide and Seek" off Speak For Yourself by Imogen Heap. (Thanks to Peter and Ben at Music For Picture and their Winter 2006 New Music Review.) Kind of reminds me of Laurie Anderson's vocoder work, and for some reason, Imogen's melody brings up fragments from "Blue Sound - Note 3" off Domino Theory by  Weather Report. Crazy.
