What is the Christian "Spiritual Anthem"?

I was listening to NPR this morning (something you do after you graduate from college), and heard a discussion about national anthems (click here for the story), which was brought on because of the imminent Olympic games.

Nationalism requires a unifying song. Thus, the national anthem.

I believe that every group of people need a melody to sing together. This is the very reason we named this next generation worship event "Anthem." God has given us music and song to bind us together. Interestingly, right on the heels of making so much of unity in Colossians 3, the Apostle Paul compels us to sing to one another with "psalms, hymns and spiritual songs..." I pray that Anthem will be a movement that binds Christians together through passionate, Christ-exalting worship songs. I pray that the Anthem melodies are epic and stir not just the individual soul, but spark a corporate movement toward the things of God.

If there was to be a Christian "national" anthem ("but you are a... holy nation, a people belonging to God" 1 Peter 2:9), I wonder what it would be?

What is your vote?
