^ Yeah, performing a song live before its release is not uncommon, especially for bands, but for Kuu it's pretty uncommon. I can only think of songs that were right next to be released, TRICK (which never got a performance again or a studio ver at all), BRING IT ON and now Cupcake. But I myself think this one will be released in the first half of 2016, I guess she has recorded some songs prior to the tour to keep on releasing stuff during the year. At least that's what I hope to be the case
