My favorite in all honesty is the χ Back Cover version. I love the organ that's in it.

My favorite is the dearly beloved in Dream Drop Distance. It looks so dream like 

kingdom hearts 2 version is the best not because of the soundtrack itself (alltough it is freaking awesome) but the emotion connected with it when you were a little kid played the first KH and than finally after years saw this game in the store and heard t he music you just KNEW it was going to be just as awesome as there first time

DDD it sounds so cheerful.

I wanted to say KH2, as that's my favorite KH. Although I'm not the biggest fan of BBS, it's still a pretty good game and I really love the version of Dearly Beloved in it. It's beautiful, it takes everything that made KH2's version so good and made it even more emotional. I honestly can't get enough of it and I can't wait for KH3 to see what that sounds then.

I love all of them, to be honest. However the DB in KH2 is just so peaceful. 

The Dearly Beloved in Dream Drop Distance is my current favorite one. I love the whole Dream theme music in Dream Drop Distance.

The BBS version always felt more emotive to me. I love how it starts out so small, the single piano notes like the quiet beginnings of a hope that gradually build up into a more firm belief. It’s like it’s saying that maybe things can be ok in the end after all. I like that.

 

Also, dat tremolo.

Kingdom Hearts II will probably always be my favorite. I really like Union Cross's Dearly Beloved, too, though. I think it's the oboe part overlaying the melody just giving it a very depressing vibe.

 

Unchained is probably my least favorite. I don't know, perhaps I just heard it too much playing the game.
