The song "Welcome to my Life," by Simple Plan, is similar to other songs in the sense that it resembles a poem. Songs and poems often sound similar because they use a lot of the same devices. For example:
No you don't know what its like
When nothing feels alright
You don't know what its like to be like me
To be hurt, to feel lost
To be left out in the dark
To be kicked when you're down
To feel like you've been pushed around
To be on the edge of breaking down
And no one there to save you
No you don't know what its like
Welcome to my life
In this song, the author employs the device of repetition. He repeats the phrase "No you don't know what its like" several times. Repetition is often used to emphasize a point or to call attention to a particular subject.
