Ayu Schedule #3 - TV Appearances, Magazines, etc.

[Bigtop]

Is there any some sort of criteria about how do artists get invited for the FNS music festival? I know about the Kouhaku at least, which is based on performance notability, but is there any similarities and differences between the FNS music festival and the Kouhaku on how do artists get invited?

And is it really sure why Ayu either did not get invited or rejected her invitation?
