Sorrow
I always loved Axel, Roxas, Larxene, and Xion from the organization. I always enjoyed this music but the cut scenes meant to go with it were always ones that either made you feel sad or upset at what they were doing. I always felt sorry for Namine and Roxas (Ventus) since it was thought they were meant to fade but they simply became one with Sora and Kairi.
I just go to say though that this is a beautiful cover. The piano sounds very sad and the synth playing choir notes in the back makes this sound like a very melodramatic cover. Very wonderful cover.
Overall, excellent cover, well enjoyed.
