Dark Paradise/ This Is What Makes Us Girls should be the next single.
And then Summertime Sadness.
The last single is National Anthem.
And these following tracks should never be chosen to be singles: Carmen, Radio, Lolita.
(Don't take it wrong! I love these songs, but they just don't have enough potential to explode to be a hit, and I had to take a long time to get along with the melody of those.)
