O Fortuna is a poem from Carmina Burana, a collection of Latin poems written in early 13th century. I do not know what is enticing about the tune but the chorus, the rhythm resonates within me. For years, I have not known the meaning of the song and now here it is (translated to english).

O Fortune,
like the moon
you are constantly changing,
ever waxing
and waning;
hateful life
first oppresses
and then soothes
as fancy takes it;
poverty
and power
it melts them like ice.

Fate – monstrous
and empty,
you whirling wheel,
you are malevolent,
well-being is vain
and always fades to nothing,
shadowed
and veiled
you plague me too;
now through the game
I bring my bare back
to your villainy.

Fate is against me
in health
and virtue,
driven on
and weighted down,
always enslaved.
So at this hour
without delay
pluck the vibrating strings;
since Fate
strikes down the strong man,
everyone weep with me!
