Ayu is suffering from the same dilemma that many veteran popular artists have to deal with.
Most people want to hear her most famous songs from her peak years ago.
Only dedicated fans will want to hear specific singles from different eras and hidden gems/under performed material.
I see it all the time here. An artist will play a handful of songs and everyone gets excited for the older big hits and then when they get to the newer songs no one cares anymore. Some people even complain when they play less mainstream songs!
So if Ayu performs new songs, there won't be a lot of hype or interest in her appearance on TV. If she performs older songs from her peak popularity, it will draw in more viewers and hype and makes her appearance more relevant to the public. She can't win either way.
She most likely is doing Music Station to support her 20th anniversary era/activities. So it would be wonderful if she would perform songs from a variety of years.
