Most nauseating song ever

I've just had to rush to the radio to switch it off (Naim being remiss in omitting a remote control on the 32.5; I've tried using a long stick, but the switch on the front is surprisingly stiff when activated from a distance of eight feet). In a show about the large hadron collider, up came Louis Armstrong singing "What a wonderful world". Why does the BBC do this? Surely that song qualifies as one of the most stomach turning of all time.
