In regards to the bridge, there are really only 2 ways to look at it.
The "weeping and gnashing of teeth" is a biblical passage. Either Kanye is praising God by saying that his music is music for the "champion" (God).
Oooooor the exact opposite, since it says "my sound which is the champion sound...Believe!...".
In my opinion, he only includes these lyrics to confuse people and draw more attention to his music.

......then theres always "illuminati"
