Am I the only one getting the vibe that these were rejected RB3-disc songs?
 
Regardless, I'm really digging La Roux's Bulletproof, and the Eagles of Death Metal, KMFDM, and Blondie songs are all pretty good. 
 
I still can't get into The Decemberists. Never have, seems that I never will.

I love that Blondie song... up until the point where she starts rapping.
 
And they picked the wrong The Perfect Crime
 
 

 
 
 
:'(

Will buy "Bulletproof" by La Roux, even if I don't really play RB2 anymore. I'll surprise myself with its awesomeness later down the road.

I'd like to see how Bulletproof is tracked.

Hm, lots of diversity this week. I'll have to check them out.
