I think GaGa is the pop artist of our generation. Everything she does is on humongous scale & she is usually a hot topic of discussion in school or at the workplace. Her record sales are huge & a level above her peers (even Born This Way - what other pop record has sold as much in the past 2-3 years?), & she consistently get hits. With a new album on the way probably jam-packed with hits, we can expect her to add significantly to her sales, & to her impact on pop culture. Dressing outrageously in Hollywood has also become synonymous with her. She is iconic for both her music & style in such a short amount of time.
Beyoncé is in second place, & Rihanna is in third. Bey doesn't get as many hits but her impact will never be forgotten. Rihanna will be remembered for numerous hits in decades to come.
