i very like faye singing this song. among singers who're still alive, she's the only one who translates the emotion of the song. she keeps making the song current, the key is we keep the spirit of the song writer, lyrics and the original singer living instead of commenting on "authenticity".
No one can sing like TT because only TT experienced her own life. No one can sing like 王菲 either. Great singers sing their own life experiences and feelings that can resonate with the audiences.
