 Where its predecessor "Reanimation" was heavily dominated by repeating guitar arpeggios and strong melodic hooks performed on guitar, they now get to take somewhat of a backseat, and in doing so enables other instruments to step forward and fill the void on this new record.The piano is heavily featured on half of the tracks, and this album also sees an increased use of synthesizers, especially in tracks such as "Heartbeats" and "Orbit".The songs on "Save Your Heart" are also noticeably shorter than on the band's debut, oftentimes reaching a final playtime of 2–3 minutes.
