What is the name of the song where Yuna tell's Tidus that she could die from continuing her pilgramage, but makes the decision to keep doing it?

... you are fighting Sinspawn Gui at Mushroom Rock for the second time with Seymour in your party? Its really catchy but I haven't been able to find it anywhere mostly as I don't know the title of it It may appear later in the game too but I haven't played through X in a while so can't remember

I just did this part last night, the music reminds me FAR too much of Dark Bahamut

What's the song that you hear in FFX kinda at the beginning when Tidus walks and stops and sees something that I don't remember lol.
Oh btw, the video i posted i found the song!
it's: FFX soundtrack-Revealed Truth.

The webpage above is the teaser page for the upcoming Piano Collections Final Fantasy XIII. I have never played FFXIII, but watch lots of its playthroughs, etc. I like some of the soundtracks, and I cant wait to learn the piano collections (especially Vanille's Theme).

My question is, to those who have played the game, what song is playing in the background in that page? Is it one of the tracks in FFXIII, or is it just a brand new music created for the page? If it's from the game, can you identify the name of the track for me?

EDIT: it seems that the background music has been changed to the main theme/serah's theme. Never mind
thanks
