How many of you noticed this in the spell casting demonstration?

So I've just watched the demonstration of the new spell casting behavior and while what was on video wasn't all that interesting. I noticed that the Nail of the Heavens BGM was altered greatly, as if it was a midi version of the song. Which have me thinking about the reasoning behind this.

Will the PS3 version of FF14 have downgraded audio like FF12 did?
Not likely sure due to it being on blu-ray but you never know.
I just find this very strange.

PS3 has no issues playing audio so no, its just probably a different version of the music.
