For reasons unknown, the Material Girl's 'Material World' has been swirling round my head. I believe this is called an 'earworm' and sadly, there is no known cure: I just have to wait for the next song to take its place.
While the song is anchored in 1980s excess (impress/depress yourself... in which year did the song come out?), it may be due for recycling. A Millennium version of 'Material World' might carry the opposite connotation - less is more.
