Help me.

I was in Macy's today, and in the makeup section, a song came on i couldn't shazam because my ipod didnt have wifi. The chorus went something like: Ohhhhwa, ohhwaa. something something something together, or forever. Its killing me, i wish they showed what they played on their site. and the beat was dubstepish, but calm.

The singer is female by the way. Any help please.
