Lukasz

anyways... I was shocked to see Mariah at the top of this list!

And slay Katy for being the biggest reason for Dr. Luke's success

Dark Horse and Birthday for 2014. not to mention LL in 2015. Lukas cant be stopped!

Only a legend

Truely a Legend. Thank you Lukasz. Best producer

Free Ke$ha though

Other than him being mean to Ke$ha, congrats Luke

Great achievement for anyone

OMG.... Seven #1s to Katy and four for Ke$ha

Can I wok with him tho. I could use some coins.

Mariah Carey would be #1 tho

Congrats Dr Luke! Big accomplishment however this doesn't make him any better of a person. he's a jerk through and through #FREEKESHA

Fixed

Queen Lavigne made this possible.

But Dr. Katy's biggest hit isn't a Luke production

Dark Horse coming too

Mariah Carey, the true queen, still reigning though

Go Luke
