The greatest female vocalists of the 2000s from all over the globe duke it out to see who has the best voice. While every artist on the list has had a great deal of success and many of whom very popular, these international vocalists were chosen for their versatility, emotion, vocal range, power and mastery in pop, rock, r&b, and country music. This list includes the likes of Adele, Florence Welch, Pink, and Lady Gaga. There is also another special criteria--all of these women have less than 20 years of musical experience, which means this disqualifies artists like Mariah Carey, Whitney Houston, Celine Dion, Mary J. Blige, etc. Fans have the power to vote on who which female artist has the best voice in music of the new millennium.
