In recent years, it seems that the dancing pop superstar has been reduced to a walking pop superstar, a star who doesn't dance but rather, walks around the stage while singing.
Prime examples include Katy Perry and Rihanna.
Even Britney and Christina, both dancing popstars in their early years, have become walking superstars.
Is it not cool to dance and sing at the same time anymore (like Janet, Paula and Madonna did eons ago)?
