And one more quick ques'

Since Rih was brought up.
What's the point of a #1 single when
QuoteDid the botched launch of Rihanna?s album dilute enthusiasm about her tour? Ticket sales have been soft?the demand is such that she?s only booked for one night in most of the arenas on the North American leg, while European stadiums are even softer. The Weeknd had been installed as special guest star for Rihanna?s European tour, but pulled out when he found out he would not be co-headlining and had to go onstage before dark. By contrast, upper-demo U.S. summer tours including Paul Simon, Sting, Don Henley and David Gilmour are doing strong business.
I guess my question is if so many people are willing to buy your single why wont they go see you on tour?
Waii!I think I know!
Is it because it's easier to pay 1.99 for the the single and just pay the album and tour dust?
