With his fizzy melodies, soaring riffs, and crisp beats, Dr. Luke specializes in explosively catchy pop. In the early '00s, he hooked up with legendary Swedish producer Max Martin to create signature hits for Kelly Clarkson. After that, he added his sparkle to dozens of pop's biggest acts, and this collection is packed with Dr. Luke anthems from artists like P!NK, Katy Perry, and Britney Spears.
