Hmmm. The thing I see about the tepid second NA leg is that she wouldn't need to find a way to draw more demand if she just promoted her music. Yes, she's doing great, but she's not hitting her peak potential. If songs like Daddy Lessons and Hold Up were ruling the airwaves, there'd be a lot more casual people who'd want to go see her because they liked her new songs.
Imagine her trying to tour IAWT without Single Ladies and Halo...
Fine...she's bigger than that today you say...I agree.
But now imagine her trying to tour today using her current starpower AND with another Single Ladies and Halo? It'd be no question of dates selling out. Singles draw people out to see the songs performed. It's just another way they help.
I hate her for neglecting them.
