5. Ke$ha & Dr Luke
She's the ultimate queen of polarising opinions, but there's no denying that Ke$ha has a knack for a killer hook and chorus. Her mentor and pop hit extraordinaire Dr Luke is, in turn, no small part in her success. He's executively produced both her records and the vast majority of her songs, delivering electropop goodness straight to the airwaves for the past few years. Given this is the man who's given Katy Perry, Britney, Kelly Clarkson, Adam Lambert and Rihanna, to name a few, their vital hits to stardom, it's a good sign. Recent album
Warrior helped reinforce this more than anything - with Kesha reinforcing her rock ideals with plenty of guitars and cool guest spots, Dr Luke built a bit of a solid pop masterpiece with absolutely incredible tunes such as 'Last Goodbye', 'Only Wanna Dance With You' and lead single 'Die Young'. The pair work well together because they compliment each other very well - Kesha's a rockstar at heart and Dr Luke is a pro at engineering radio-ready pop smashes. Imagine what they could do if they planned world domination. Maybe they already have.
