In reply to Linda.

Katy Perry is always playing with payola and discounts. She has built her career on that and on basic enough music to please certain groups of people. I would feel bad about myself if I were an artist and had to do what she does. Rihanna is another queen of cheap tricks based on singles which never comes accompanied by real huga albums success. At least others evolve and have real talent, even if they are not on the charts or maisntream refuses to support them.
