I've done this track before, but it's such a good track I re-did it to add a better sound to it. I absolutely love this track with all my heart, and the emotional bond I have with this track just keeps bringing me back to it.
I'm personally extremely glad they re-did it for the Kingdom Hearts 2.5 remix. All the remastered OST in it sounds amazin'.
The actual title for this track is Sinister Sundown.
