Recently, I played a match with my friend in Dissidia Duodecim. He formerly had a pretty mediocre play style (no offense to him), but in this most recent match, he played with a character I'd never seen him use before and displayed unprecedented skill that was quite surprising. It was certainly one of the most exciting matches I've played ever in all the history of Dissidia. Therefore, I'm currently in love with the theme that I put in the video of the match, a remix of Blinded by Light from Final Fantasy XIII.
Furthermore, this won't likely be permanent; my tastes tend to change as obsessions move in and out of the picture. Among other music from the series I like:
The Extreme
Loss of Me
Those Whom I Must Protect
Mambo de/Fiddle de/Aloha de/Retro de/Ukule le Chocobo
Premonition
Those Who Fight Further
To Zanarkand
Dark Messenger
So on and so forth.
