i'm not saying that she's only had her songs produced by Dr.Luke and Max Martin, but her biggest hits have and I can fairly say the majority of her hits have relied on one of those two.
And mess at Womanizer being a smash success when you guys call CIL a local flop even though it did better in nearly every (relevant) market .
But Womanizer was a bigger hit than anything that was produced by Luke and Max except BOMT.
Hell, the Lazy Jay produced Scream & Shout was a bigger hit than any of Britney's singles post-BOMT.
Gaga needs to hire a ghost writer ala Bonnie McKee for her verses, both Applause and Aura would be A+ amazing pop-songs-of-the-year material if not for those verses I just can't get over how they ruin the song so much.
