Bad Religion is always a good thing. Too bad we still don't have anything off of Stranger Than Fiction, and they probably should have picked "I Want to Conquer the World" instead of "No Control" if they really wanted a song off that album. Oh well.

Hell yeah, Stooges. I'll check out the Bad Religion tracks.

Awesome, about time we had some more Stooges in the genre. The fact that its marked as "Pack 01" is quite interesting, would like to see whats in future packs.

Yes The Stooges are awesome!

Would have preferred an all Bad Religion week, but whatever :(

" @sofacitysweetheart: That's where we will have to disagree. Personally I think Bad religion are a terrible excuse for a punk band. "
