Does Ayu's voice ever hurt your ears?

[Norrel]

This isn't meant to be a mean or funny post, but lately I've found her voice to be EXTREMELY difficult to listen to in some songs where she sings high notes.

For example, UNITE and Hello new me have a few parts in the chorus where I literally have to turn down the volume because there's parts in their choruses where her voice creates a sharp pain in my ear.

I'm not sure if this is just bad mixing or bad EQ settings on my part, but it's been a problem for me and I wonder if anyone else has experienced this with her voice on some songs?
