Ok London it's our last artRave together. The past week has been so wonderful, let's burn a hole in the road tonight.
This sounds a thank you letter and BTWB is her reward to them, why quote a MTN?
February 2015 : Grammys, just before the tour. So if it snatches a Grammy, people will be interested
February 2015 - September 2015 : C#1C Tour. I don't see it being longer. We already have an European date in June. I'm gonna guess and assume they're going to tour the US first (4/5 months) and then come to Europe and end in Asia.
Around November, announcement about new music + possible release. Depends if she already has material or nah.
That's how I see 2015
That's one thing also she said she will be at the Grammy's next year so
Nah....but she most probably would perform on a piano cause I doubt she'll take her dancers up there too.
90% chances of this on lock 
But I guess it was just at a wrong spot in the order.
It was the song I was the most excited about when I first saw the videos. Damn
