16. Choose Your Battles
Similarly to Who Am I Living For from Teenage Dream, this track concentrates on the analogy of war and once again it can be assumed that the song is about Russell Brand, although this is not explicit and could refer to any one of Katy's previous loves. As one of the bonus tracks on the deluxe version of the album, I feel that this song leaves a lot to be desired and is not necessarily the best track to end the album on as it is distinctly average. Rating: 4/5 Katy Perry's new album, Prism, is by far the best of her studio albums up to this point and as an artist, Katy continues to grow. Although the last two years have no doubt been heartbreaking and difficult to get through for Katy, the way in which she has shaped her feelings to create this album is outstanding and will not leave you disappointed.
