For the song analysis I found the song "Firework" by Katy Perry. This song popped into my head when Dr. D first assigned this assignment. The first literary devise I found was right in the first verse.

"Do you ever feel like a plastic bag
Drifting through the wind
Wanting to start again"

With this verse I saw a simile being used. Like a plastic bag was what stood out to me. I interpreted the simile because it is comparing the person to a plastic bag using the word "like." I took this simile's meaning as when you feel like a plastic bag, you feel sort of disposable in a way. I also thought it could mean that you are ignored. I found another simile in the verse right after this one. When she says "Do you ever feel, feel so paper thin" refers to the person thinking of themselves as invisible to someone or something. That's how I perceived this simile. 

There were many examples of anaphora, for instance the line "Do you ever feel" is repeated multiple times at the beginning of the verses. I found one example of a personification in one of the lines.
"If you only knew what the future holds"
This is a personification because the future is an inanimate object and therefore isn't actually able to hold something.
