Song played during last battle

I'm wondering if anybody can tell me the name of the song that plays during the last battle (the one with Trance Kuja, not Necron).

Thanks :)

It's called Dark Messenger. FF9 OST, Disc 4, Track 15.

Thank you! :) *goes to download*
Me and my friend just love that music..she says it reminds her of Queen's "We will rock you".

You're welcome. About the song reminding you of "We will rock you", that's because the beat in the beginning is very similar. The song "Immoral Melody" also has the same beat in the beginning. Immoral Melody is a song that plays a lot when Kuja's around, and it has pieces of his theme.
