I thought about this for years.

I've always liked Mya and wondered why sis always got lost in the shuffle,
One, she came out in '98, too late to really be part of the Li, Bran, Mo group. She didn't have the homegrown young teen fanbase they did since she came out at 18. It isolated her.
Two, she could never maintain momentum after big singles. She'd have like one or two, and then disappear. The nineties and early 2000s were all about multi-single eras. She didn't have a memorable string of singles or truly classic albums. Sometimes it wasn't her fault. I put a lot on her labels. What was the single that followed Case of the Ex? Why did Fallen flop?

Three, she didn't market herself personality-wise. She's always seemed aloof. Even in the era of TRL, reality shows, Cribs, Making the Video, etc. I can't remember her making her presence known.
Nevertheless, she won Grammys, made hit singles and collabs, performed for MJ, acted, did DWtS, and she's still recording and cute. Can't win em all lol.
