My pick would be boyz II men. Over 60 million record sold. Debut album spend 133 weeks in the top 4 billboard charts. 4 Grammys. 9 American Music Awards. 3 Soul Tran award. 2 mtv music awards. 3 #1 songs in the span of 14 weeks. And besides all of those accomplishment, their songs are endless. I pop in their music whenever i bring a girl home to my house and have some romantic night. Do you agree with me or do disagree. If so, please let me know who is the greatest r&b male vocals of all time.
