FOREVER 21 song..."sun was shining"...

I was at the Forever 21 the other day and I heard the most awesome song...the chorus was something like "and the sun was shining, and the sun was shining...etc.etc"

that's all I really know! It had a dance beat and a soft high pitch female voice. The song talked about being "in the city" and wanting to stay that way...

Who sings this song? It is so catchy! Anyone? Anyone?
