One of my favourite videogame pieces:
MP3 at http://www.ffextreme.com/ff4/music.html
Please don't just post a transcription of the "FFIV Piano Collections" sheet, as that misses out a lot of the piece.
Not that nobody will do it here, but I noticed that the sheet is on Ichigo's. (http://ichigos.com/sheets/fi)
Though it could be the piano collections version you talked about, I didn't check.
Actually that one is completely wrong.
It doesn't even appear to be from FFIV at all.
