I believe the first is Scott Stapp, openly Christian, while the second is mainstream. However, it may be the other way around. I have Scott's latest spinning in my truck right now, and either set of lyrics here would fit the tune for the song that was playing just before I sat down at my computer. Sadly, I don't know the song names or words without looking yet.
Of course, I could be completely wrong! Shall we ask the Mrs.? Never mind ... I already know her answer!
Edit: Just checked my answer, so I know I got it right per the game rules ... just missed the bonus points by a long shot! I shoulda gone with my gut, as I almost said Petra! LOL!
Here's my contribution:
First SetYou'd better run, forget your pride
Don't make a stand, just step aside
If you don't have what it takes
Don't try to play you'll lose your stakes
Second SetSacred servants sacrifice in the dark of night
Helpless children scream in fear, to my delight
Soul destruction, blinding eyes with godly power
Fooling mankind, making dull the light of truth
G/F - you definitely should get this one!
