"Part of Me" (3:35)
Producer: Dr. Luke, Max Martin
Writers: Katy Perry, Lukasz Gottwald, Bonnie McKee, Max Martin
Having narrowly missed beating Michael Jackson's record for the most Hot 100 chart-toppers from one album (the sixth "Teenage Dream" single, the fittingly titled, "The One That Got Away," only climbed to No. 3), Katy Perry takes a fresh start with "Part Of Me," the first of three new tracks from a forthcoming re-release of "Teenage Dream." Much has been made of the breakup jam's supposed jabs at ex-husband Russell Brand, but the song was actually written during the 2010 sessions for "Teenage Dream." Post-divorce lyrics like "You can keep the diamond ring/It don't mean nothing anyway" notwithstanding, "Part Of Me" is a dancefloor rave-up in the tradition of the "Dream" team of Dr. Luke, Max Martin and co-writer Bonnie McKee. The song also brings to mind Jessie J's "Domino," another Dr. Luke confection, chugging along to a similar treadmill-ready groove and riding a guitar hook. And, as Perry already previewed at this year's Grammys, the song has potential to become a live favorite, perfect for fists-in-the-air sing-alongs.
