I think a lot of people are amazing vocalists...it's impossible for me to choose just one.
Chris Martin (Coldplay)
Freddie Mercury (Queen)
Elton John
Madonna (at one time lol)
Christina Aguilara
Lady Gaga (
yes I think her voice is good lol)
Beyonce
Florence Welch (Florence and the Machine)
Adele
Mariah Carey
Shania Twain
Alan Dawa Dolma (most of the time she sings in her average voice, but when she shows off her mountainous vocals...it's breathtaking)
Utada Hikaru
Emi Hinouchi
ayaka Lida (such a beautiful voice)
Hyorin (SISTAR)
That's all I can think of at the moment...but I know there's more
