The reason Mya fell off was because she simply couldn't stand out from other popular female acts of that time. For example look at Lady Marmalde Mya was totally upstaged and forgotten on that song. To make things worse she had such huge competition among the likes of Aaliyah, Britney Spears, Christina Aguilera, J.Lo, Pink and much more. Mya just couldn't stand a chance because her songs were just blahh aand didn't have the passazz it needed for her to stand out against other popular female artists at that time.
