An extension of its satiric predecessor, "Windowlicker" focuses on eerie lounge-porn music (with a video to match) instead of the thrashcore of "Come to Daddy." Later Aphex trademarks like hyper-breakbeat drum programs and heavily tweaked voices are in full effect, though the cloying melody could make longtime fans run for the toilet (or fall off the couch laughing).
Of the two unpronounceable B-sides, one includes more breakbeat thrash, while the other looks back to Selected Ambient Works territory with a toybox melody that's only potentially disturbing.
The enhanced single also included the video of the title track, directed by Chris Cunningham, and possibly even more disturbing than "Come to Daddy.".
