Missy was just as dark, and FATTER, and made it all right. Kelly blaming her mediocrity on her skin color is foul
Missy wasn't part of a group
Missy also was a producer, she had ALOT of creative control over her sound, image, lyrics, etc.
Missy was part of the Timbaland, Ginuwine, Aaliyah, movement and had very close ties to all of them. She benefited greatly from that movement (and also Greatly contributed to it)
Can't really compare Missy to Kelly. Kelly came in as part of a group, and was second banana WITHIN that group, and it so happened that the MANAGER of that group was the lead singer's father. I'm not going to exaggerate and say that Beyoncé isn't talented and worked hard to get to her position, but she CERTAINLY had the "push" earlier and with more vigor. Kelly isn't "foul" at all, she's had really good music and albums that didn't get a very push at all
