I don't relate to you I don't relate to you, no
'Cause I'd never treat me this shatty
You make me hate this city
And I don't talk shat about you on the internet
Never told anyone anything bad
'Cause that shat's embarrassing, you were my everything
And all that you did was make me f.. sad
So don't waste the time I don't have
Don't try to make me feel bad
I could talk about every time that you showed up on time
But I'd have an empty line, 'cause you never did
Never paid any mind to my mother or friends, so I
Shut 'em all out for you 'cause I was a kid

The song name to this is Happier Than Ever by Billie Eilish

Explanation:

relief sculpture - images are set against a flat background.

a coin is a good example: the inscription, the date, and the figure are slightly raised above a flat surface. the ancient egyptians sometimes carved figures into a flat surface.  

pro: they take significantly less time to make and do not require as much tools or skills as free-standing

cons: not nearly as realistic, as it is not fully 3-d, and does not have the details that a free-standing one does.

freestanding sculptures (also called  carved in the round) are not attached to any  background.   they are 3-dimensional  and fully rendered.
