dfddddd. Did I just read Rihanna doesn't need Pop radio?
That's her bread n butter. She doesn't have a loyal fanbase like Madonna, Britney, Gaga, Taylor, or Beyonce.
And increasingly, Katy. She's one of the few popstars who's only as good as her last hit.
Either that or her loyal fanbase is too cheap (read: poor) and don't buy her music. Her first weeks sales are inexcusable for a popstar of her caliber.
Either way, she needs constant radio exposure to maintain steady sales.
