A chant rather than a song, but how about the magpie count? This is the version I knew

One for sorrow
Two for mirth
Three for a funeral (or wedding)
Four for a birth
Five for sil'er (silver)
Six is gold
Seven a tale should ne'er be told
Eight is Heaven
Nine is Hell
and Ten is the De'il in his own sel'

5-8 don't seem to quite match with the rest.
