If she doesn't start acting she should really work on more soundtracks. I could definetly see Shades of Cool or Burning Desire being part of a James Bond movie.
I had no idea she was depressed with happy songs such as Summertime Sadness and Born to Die.
But if you read between the lines of those songs they reveal happiness.
Summertime Sadness is not only about sadness.... the singer feels joy and content with what's happening "I'm on fire, I feel it everywhere", "I'm feeling electric tonight, cruising down the coast" etc.
for her recognizing that Britney is actually dead.
