Hey friends, I've been working on this paper about figurative languages used in the song 'grenade' by bruno mars. The link for the lyrics is below www.metrolyrics.com/grenade-lyrics-bruno-mars.html . I've already done the attemp, I just want to make sure and need help from you guys if I got these right or what is better. So what I got is as below:

easy come, easy come -> idiom, meaning taking things very easily, not caring about others' feeling.
gave you all i had and you tossed it in the trash -> literal, like he didn't really gave her everything and she didn't toss it in the trash.
i'd catch a grenade for ya...i'd do anything for ya (whole stanza) -> exaggeration, he's not gonna do all that.
i'd go through all this pain...straight in my brain -> exaggeration again.
black black, black and blue -> idiom used for beating till he gets bruises.
tell the devil i said hey -> i dont know, is this a hyperbole?
if my body was on fire -> literal, its actually not on fire.


any corrections or suggestion would be appreciated. Thanks, abodhBaalak
