Which One-Hit Wonder Had The Best Hit?

I'm kind of torn on this. Norman Greenbaum's Spirit in the Sky has been a radio staple since it was released and has been on movie and tv soundtracks (and if Wikipedia is to be believed, highly requested at funerals). But Lipps, Inc.'s Funkytown was also a (massive) hit when released and was, by memory, on the charts with Pseudo Echo.

Whatchagot?
