Carey's vocal style, as well as her singing ability, have significantly impacted popular and contemporary music. She has consistently been cited as one of the greatest and most influential vocalists of all time. As music critic G. Brown from "The Denver Post" wrote, "For better or worse, Mariah Carey's five-octave range and melismatic style have influenced a generation of pop singers." One of Carey's biggest milestones has been to "close out the '90s on a very high note" after being named Billboard's artist of the decade in 1999. MTV writer Erika Harwood wrote that "she is also known for ruling the '90's from fashion to music."
