Momo looks adorable (as she usually does! XD) I really like how her face turned out~
I hope they keep a rock theme in this single, but maybe a soft rock? They can change to something new that's refreshing, but I just hope they keep the overall theme that made me love them instead of becoming a more generic idol group.
I don't think it'll be rock, the covers don't look like it and on the blog they said they went back to old Buono! (more cutesy? more idolish?) And I think Buono! can pull off any style actually, I don't want them to stick with one style all the time, and recently we had a lot of rock.. personally I hope for something like Take it Easy
Maybe they mean more idol-pop with random rock overtones. From their second single onwards, you could tell they were going to be rock-themed (there were guitar riffs in the first single, but not much more than any other modern idol song.) So if they are going back to the old Buono, it will be cute rock that experiments with different genres.
I actually didn't like Take it Easy so much, probably my least favorite song from them. It was more country rock. XDDD
