This weekend, Mariah Carey is set to launch "The Elusive Chanteuse Show," her first world tour since 2006.

Is that a surprise?

Well, like pretty much everything else the Greenlawn native has done this year, aside from her very public split with husband Nick Cannon, it isn't getting much attention.

The first leg of the tour starts in Asia and ends in Australia in November. No word about any American dates, though the tour is expected to extend into 2015, as she promotes the critically acclaimed, but commercially underwhelming "Me. I Am Mariah . . . The Elusive Chanteuse" (Island) album.

"I want to experience the spontaneity and emotion that I put into this album on stage with my fans," Carey says in a statement. "I can't stop writing songs, so don't be surprised if you hear a brand new song that I just wrote the night before the show in your city!"

As far as Carey is concerned, she's moving on -- even if she's already put her best high-heeled foot forward and been basically ignored. After all, she's not the only one. Radio's lack of support for Beyoncé's singles, for example, reinforces how song quality is only part of the equation when it comes to airplay these days. In a way, pop radio stations' avoidance of Beyoncé's "Flawless" undermines the importance of the stations to overall sales for some releases. However, their avoidance of Carey's "You Don't Know What to Do" shows that airplay is quite important to her sales.

In the long run, though, Carey may get the last laugh: A Time magazine study of pop superstars found that Carey is the biggest of all time when it comes to producing hit singles. Odds are, she's not done yet.
