Black Eyed Peas used the figure of speech apostrophe in the lyrics of the song:
Father, Father, Father help us
Send some guidance from above
'Cause people got me, got me questionin'
Where is the love (Love)
Apostrophe is addressing someone or something that is non-existent or a third party.
"I feel the weight of the world on my shoulder"
This line uses hyperbole. It's an exaggeration.
