Alright, there are some famous missing tracks for the SquareEnix DS title The World Ends with You, but every place I've searched only has the same 6 or so, and not the one I want, which is also missing from the game's OST as far as I can tell. It's a slower, more sad and wistful background tune that plays at a few times during the game, but most notably during most of the ending dialogue after beating the final boss. You can hear it here: YouTube - The World Ends With You Walkthrough - Part 62: Beat - Seventh Day[6 of 8] - FINAL BOSS (http://www.youtube.com/watch?v=bbgWV2oNyiE) at around 6:04. Does ANYONE know where I could find this tune? I'd be very appreciative of any assistance on this.

The track is called "Amnesia", and is on the Original Soundtrack as track 18 of the soundtrack. You can buy the soundtrack off of Play-Asia. Hope this helps.

My God, I feel a proper fool indeed. Apparently, the source I downloaded the soundtrack from had this one tune inexplicably missing, and I didn't notice the jump in numbers that would indicate its absence. I never actually looked at the regular soundtrack anywhere else, just assumed it must be a missing song and tried to find it under a search for such. Thanks a lot for pointing this out to me. Sorry for my dumb mistake!
