Lyric discussion by Bamerella 

Cover art for Who Cares? lyrics by Gnarls Barkley

Code Azul

I see a lot of signs of someone in recovery(from addictions) in a few of Gnarls Barkley's songs. I interpret the fourth verse to be about having a second chance at living life. The other verses (particularly the 1st and 3rd) seem to relate to recovery as well, although I like your interpretations as well.
