Does anyone know how to get the extra songs?

I know there are extra songs, but I don't know how to get them. I know at the end, all I had gotten was Wakka's theme, and Lulu's Them, but that was it. . .I couldn't get the other ones.

And I heard that there are extra movies too. . .is that true? :confused:

Wakka's theme, Lulu's theme and the Hum of The Fayth are all you get. There are no movies.

Oh, okay, thanks!
