I like the song really, but it sucks to hear about her voice. I'd imagine Maki knew she should have given her vocal chords more time to heal properly had chosen to continue bringing music to everyone. It is not easy wanting to do what is right and not dissappointing their fans. I can only hope that she focus on herself and takes the time to get better before making another comeback.
Name of the song makes me think of Pat Benatar. xD
But yeah, there's a slight tinge in Maki's voice that you can tell she was skeptical about being there.
