a selfish mystery

I've been selfish of late, neglecting you in favour of triking, XBox or other mundane pursuits. Motivation is in short supply. But I miss you, and promise to try harder to keep in touch. The mix tonight is a mystery theme. It's esoteric, but anyone listening could divine it without much effort. What is it?
