The singer, whose re-swizzled version of GaGa's song 'Telephone' featured on her remix album, believes she has made it easier for new artists to break into the industry.
He told MTV: "She's pretty much changed the whole game with her music and her videos and her style and all that.
"It's like blown everybody's minds and it just got more and more crazy and more and more brilliant. It just kept going.
"I guess she pretty much changed all the rules of pop music. Pretty amazing, actually... it makes way for new types of music to be played on the radio."
Anders also said GaGa's success means her chart rivals will have to up their game if they want to remain successful.
He added: "If I was Christina Aguilera, Britney and all those, they have to come up with something really, really great now.
"You can't just copy what she's doing. I guess all those big popstars are gonna sit there and go, 'What do you do?'"
