haha, totally agreed..if you're not being sarcastic...
From a business standpoint, I see no problem with this tour at all; and I'm actually surprised at all the hate comments towards the lineup. I feel like both artists have the same audience as of their current radio presence and records released.
In simple terms:
2 current and/or recent Top 40 artists + teenage girls (and other listeners) audience + parents' money = more ticket sales = profit!
good pairing, just sayin'
