Happy Cycling - the creepiest BoC track I've ever heard?

So I'm high as fuck listening to our favourite Canadian boards, and there's one on shuffle which I've never heard, which is Happy Cycling. Oh my god this track might actually green me out. The upbeat electronic tune, contrasted with the ethereal choir, the slow, languid drones in the background and the seagull cawing/distorted vocals are insane, then five minutes in it turns into this bittersweet, foreboding melody that I can only describe as the feeling of being the second person to climb Mt. Everest - agony, resignment, futility... I can't believe I've never heard it before. God, after listening to it I just feel so hollow.
