Hyperbole "Born to a throne, and stronger than Rome." This is a hyperbole, because a hyperbole is a extreme and obvious exaggeration, because the author of this song is obviously not stronger than Rome.
Repetition "When I get older I will be stronger just like a waving flag,waving flag,waving flag." In this part of the song this phrase is repeated 3 times. So this part of the song is repetition, because repetition is when you repeat a word or phrase.
Onomotopeia "Give me freedom give me fire give me reason take me higher" This is Onomotopeia because higher and higher sound like they rhyme but they don't
Imagery "Out of the darkness I came the farthest" This example of Imagery is used to represent the author of this song and his "dark" past, and how he still got to succeed.
Simile "Cause we just move forward like Buffalo soldiers." This is a simile because the author of the song compared himself with Buffalo soldiers (They were African soldiers.) Which are two really different things.
Voice "But its my home, It is all I have known." This part of the poem is Voice, because the author of the song is telling the poem (or song.) And this is Voice.
