Figurative language in songs
"More than a feeling" by Boston
"As clear as the sun in the summer sky"
"As clear as the sun in the summer sky... " is a simile. This simile is a great way for the writer to express that people come and go and life can be hard but you just have to keep going. Things will become more clear and easier as you go. How i got the first part is before the simile there is a sentence that is "so many people come and gone yet I still recall as I wander on as clear as the sun in the summer sky " shows people come and go but you just have to keep going and thing will become more clear.
"I don't want to miss a thing" By Aerosmith
"I just wanna stay with you in this moment forever , forever and ever"
"I just wanna stay in this moment forever , forever and ever......" is hyperbole. The hyperbole statement is a great way for the writer to express his passion for her but really you cant stay in one moment forever. Which hyperbole means exaggeration. So yes Steven Tyler was exaggerating in this lyric.
"bringing on the Heartbreak" Def Leppard
"You're a mystery, always runnin' wild"
" Your a mystery ,always runnin' wild ...." is a metaphor. This metaphor is a great way for the writer to express that she is a mystery that is free and always runnin' away. A metaphor is comparing two things without using like or as. so yes Joe Elliot ( The lead singer of def leppard ) is comparing runnin' and her being free to how she is a mystery.
