If Lana Del Rey playing AEG-owned Terminal 5 means anything, y'all could be in for some fights with psychotic stans next year. I'm still scarred from her Gov Ball 15 set
I think it probably means that the days of Lana true-headlining are over. I could see her in the Solange or Alt-J spot though.
Given how fast these two shows sold out I doubt it. These shows are probably to hype up an arena tour next year. Remember, she played ampitheaters in the summer of 2015 and was actually selling some of them out (as in, filling the ENTIRE lawn).
