Back then 100,000 or more units sold was considered note worthy, but back then they didnt have piracy, and other illegal downloads and itunes selling music for 99cents. Today there are so many means of free download that "selling" even 10,000 units or complete albums (not just one song or single) is considered a success. Therefore selling over 50,000 units or the complete album not just a single song is a big deal...I mean ppl could have just downloaded a song they liked for free or bought it on itunes for less then a dollar, but to buy a whole album..that proves mariah is still the shit...comparing Rihanna to Mariah is an insult...bitch got her fame from a beat down...and her voice is all studio work and zero talent...the day that bitch can hit a whistle register and a 5 octave range is the day that you retards can compare her to mariah..but for now she is a sad battered, confused about her hair colored bitch
