Some of my friends are WAY into lists. I figured I could start a list of my own. Here are a few of the songs that I like to sing loud. These are the songs that when they come on, you crank it up, roll the windows up (or down if you're confident), and get a drink before hand because your voice will be horse by the end. Here is my preliminary introduction to songs that I sing loud :

Hillsong - You Are Here (The Same Power)
Muse - Shrinking Universe
Blindside - Sleepwalking
Greg Laswell - I'd Be Lying
Led Zeppelin - Immigrant Song
Underoath - It's Dangerous Business Walking Out Your Front Door

That is just a taste. We'll see how it goes as my memory comes to me but one of these songs was being blared today and I figured I would let you all in on it. Parts of these songs seem like they shouldn't be sung loud, but once you get to the epic moments....sweet mercy. Beware everyone.
