Yeah, I can understand people seeing urban influences in Beat Again (as I said, it sounds like some songs by Akon/Colby O'Donnis/Kardinal Official, etc.).
But some of their other songs, especially One Shot, Eyes Wide Shut and She Makes Me Wanna, are pure pop. The same as what Britney Spears and Madonna do.
Characterists of RnB and hip hop songs are that they have a slow tempo, syncopated percussion patterns (usually with snares, kicks, etc.), instruments like piano, strings, guitar, and so on.
She Makes Me Wanna is insanely fast, similar tempo to the likes of On the Floor and Born This Way, has NO percussion in at all (well, almost none), and all the instruments are completely synthesized (it uses the same electronic sounds as songs such as More by Usher and Dirty Dancer by Enrique Iglesias, two other pure pop songs). So I would say that song in no way can be considered even slightly urban.
