The song uses Metonymy to talk about the girls funeral. "Send me away to the words of a love song", it means that the words spoken as she is buried are filled with love and longing. This line is repeated several times. Another line that is repeated a lot is, "the sharp knife of a short life". This is a metaphor because it is saying that a life cut short is always the most painful. Another metaphor in the song is "I'll be wearing white when I come into your kingdom". She is talking to God saying that she will be in heaven where everything is perfect. A paradox that is included is "what I never did is done" she is saying that what she never got never will be.
"A penny for my thoughts, oh no, I'll sell 'em for a dollarThey're worth so much more after I'm a goner
And maybe then you'll hear the words I been singin'
Funny when you're dead how people start listenin' "
This whole stanza is the whole songs purpose, this is why she is talking about dieing young, so she can get noticed and people will listen to her and not just brush her away, because you never know how much time you have.
This song is perfectly balanced in its music. If it were any faster and it would ruin the message of don;t underestimate life. If it were to be any slower it would make the song to sad and depressing. It is also very good to music in general because when you just read it, it sounds like a suicide note and that was note the goal of this song.
