"Blinded By Light" is the main battle theme of Final Fantasy XIII and one of its most prominent tracks, its theme being a leitmotif for the main character Lightning. It was the first piece written for the game, created for the game's E3 debut trailer in 2006. It was composed by Masashi Hamauzu, who wanted to create something with a catchy melody without being too straightforward. Unusual for a battle theme, it features violins as the main instrument accompanied by strong percussion.
