I think she should just move on to her next album.
But if they were to release another single it has to be either Off To Races or Diet Mountain Dew.
It should feature a rapper specifically Kanye since he loves Lana.
Could you imagine?
Off To The Races (Feat. Kanye West)
Or
Diet Mountain Dew (Feat. Kanye West)
Both can be multi format smashes urban, AC, urban AC, pop etc.
