 Philip Lawrence notes "we all have a little bit of OCD" and Mars acknowledges he sometimes has trouble letting his songs go. Mars is an obsessively detail-oriented musician. "Every day we hear a song that we produced on the radio, me and Ari call each other up at 2 o 'clock in the morning:' We should have left that snare in. '' We should 've took that snare out,'" Mars said. "It's just a sickness that we have."
