I don't think it's just to improve sales. People like those songs for a reason :/
Namie has always been more about performing and dancing than anything else...so that's what she mainly does.
And it's not THAT crazy for Ayu to think about electropop in that way. In the golden age of remixing back in the day, she was all over that scene
Guess it wasn't her original studio versions though.
Honestly, I don't know how I feel about her promotion. She always seems so busy and tired, and people are always saying how she needs more time for her.
Was there a time when she had a good balance? Instead of just either or? idk.
