Since there's been a little bit of a dry spell lately, I'm going to finish the rest of May releases in one post:
Manchester Orchestra - Simple Math
The Cars - Move Like This
The Lonely Island - Turtleneck and Chain
Lady Gaga - Born This Way
Death Cab for Cutie - Codes and Keys
There aren't any albums I would skip but make sure you especially look out for Lady gaga and Death Cab for Cutie.
