I wouldn't call it 'so successful' but it did ok considering RnB is not as popular as the way it used to be despite there's still some major success such as The Weeknd.
Back to OP, i think the main reason is that there is no release from other major RnB artist. So actually there's almost no competitor.
The new genre will be 'Ciara'. Making her mark in music.
You mean *continuing* to make her mark in music. Queen has been a force since Goodies, as demonstrated by her continued slayage in music, fashion, videos, touring, live performances, TV, and of course having the #1 female R&B song of 2015.
