In reply to MelyB.

Jessie J was successful with Domino though, even in the US.

It is nice to see you compare both artists.
When we do so, we see that in this music industry, Jessie J can stand out with her big, soulful, and powerful voice while Rita's voice is very basic, she doesn't bring anything special.
So she really needs to bring something new with her own sound and music.
