I'm honestly not so sure about this summer. Half of me expects her to pull a single out of nowhere, but the other half of me is hoping she won't, simply because I don't know when she'd have the time to create a decent one. (three versions of fairyland, BLUEBIRD and glitter are enough for me).
However, if she does pull something together, I am hoping for a cheerful song dedicated to her fans. From the posts she's been making during the tour, it seems like she's really enjoying every venue she visits, and I think it would be great if she used those positive feelings toward new material. While I hope it is musically lighthearted, I also hope it is stylistically interesting, not just pure pop. My far off wish is that she herself would compose it...
