Is this Christian???
No. Thats MTV. My kid has a POD album, and I listened to it, read the lyrics, read what the actual band members had to say - who they thanked, etc... and I found that they DO have a message of Hope and Salvation - they are also incredibly popular with the kids. So, It's no surprise that MTV would lump them in with the other popular groups of the day.
Slip Knot is definitely not Christian. Stay away from that one.
The others I have never heard of before.
That ol' devil rock 'n' roll....
