I'm genuinely curious about something though...
Isn't she able to sing songs like "M" in the original pitch anymore? Is it because of the ear loss thing?
for example:
https://www.youtube.com/watch?v=mxMRwemx5WQ << this performance of M sounds like an entirely different person singing it.
I don't mind her changing the octave and singing it lower, but I'm curious because her voice has really become something different entirely.
