Pop Song is an oddity. I got it on one of those tiny mini CDs you used to be able to get. It is an odd little song, and not, as it’s title suggests, very poppy at all.
However, it is a good song, and contains elements that suggest at some of the work that he went on to do. In some ways it seems to be a sort of experiment for him. Investigating sounds and textures and I like it for that as much as for the song itself.
