Xtina can do any style of music and kill it as long as the songs and videos are good and timing is on point.
Hopefully, she doesn't get too engrossed in a sound or theme (electro/pop, retro r&b, empowerment) and does an album thats more eclectic. Concept albums tend to backfire on her.
It was very genius and risky of her to go from Stripped to B2B. Hopefully she can release another great album like those two again
