Some great ones listed already. I really like God of Wonders, Shine Jesus Shine, and Shout to the Lord.
After college, I led a youth group at a small Baptist church and one Sunday I had them sit in a circle with a huge box of those pull-string "fireworks" that pop and shoot string in the air. The kids would each pull as many as they could during the chorus of the song Shout to the Lord.
Also Testify to Love is beautiful and if you haven't heard Canticle of the Turning it is a powerful worship song about God's justice, power, and mercy.
