By this point though it's not even a case of her just shouting or overacting, she's barely holding the tune. Compare these versions of TO BE, yes the song may be nearly 20 years old but it could be adapted to better fit her range so she doesn't sound so out of tune.

It's fine for people to still enjoy her performances, but for me there's nothing enjoyable about watching her perform anymore. I think I'm being spoiled with that youtube channel that's uploading all her old lives, but I'd rather watch them and be filled with nostalgia of how Ayu used to make me feel.
