Lol I seem to be a minority.
I would have preferred ballads. Like... Really touching, sad, nostalgic ballads. I mostly love Ayu for her ballads and for some reason I have always considered her a ballad singer.
But I would love anything from her! Upbeat, rockish, ballads, mid-tempo. Actually I equally enjoy almost every her album (except LOVEppears, but it's growing on me lately), so I'm really looking forward to whatever she releases. And actually I agree with pepper, the best outcome would be if she included a bit of everything in her album: cheerful pop, electronic dance track, fierce song, tragic ballad, something nostalgic, R'n'B etc.
