A song that will last forever. I believe Roar is a power song, it revitalizes you. I know that ever since Katy Perry became known I have loved her music. This is coming from someone who grew up on 70's and 80's music; but you have to roll with the changes. Katy is a musician that combines all genres into her music, that is why she is so successful.
