Darker songs (be it because of lyrics, instrumental, both or whatever) are definitely my favourite, but I never hope too much for her to make new ones because she said she writes songs depending on how she feels, and I obviously hope for her to feel good. So, reading what she said about dark lyrics, looks like ayu hit my sweetspot. I wouldn't mind something apparently upbeat and happy-go-lucky but with actually melancholic lyrics such as fairyland; also, I second who said an alterna-like song would be awesome for the internet bullying theme.
