Also Husker Du - Candy Apple Grey. Don't know if it counts since it's an album rather than a song. Which I know about entirely because I Googled for it, because of...

The PWEI song is called "Candydiosis". I think it's relevant enough in this thread to quote the entire lyrics.

Pop Will Eat Itself - Candydiosis

Candy says, candy girls, candy apple grey
Psychocandy, candy man eats candy every day
Candy this and candy that whenever I'm out walking
I wish I could go through the day without some candy talking

What's so fucking good, what's so fucking good about candy?
(Psychocandy, candy girl, candy man, candy talking)

(repeat to fade)
