Rise by Skillet. I really relate to this song because it's about changing things that are negative and bad and trying to make a change. The lyrics that I relate to the most are "In a world gone mad,
In a place so sad!
Sometimes it's crazy
To fight for what you believe!
But you can't give up,
If you wanna keep what you love!"

I know the song is about war...but I think it relates to every part of life, and I'm always trying to change things that are bad in my life, and it's true that you have to fight for what you believe
