Katy Perry has been in the news quite a bit recently, due in no small part to the release of her new video for 'E.T.'...That and the out-of-this-world present she bought for her husband Russell Brand. The music industry is filled with writers and producers who create lyrics and music, sometimes for specific individuals. And sometimes, those works get used by others instead. The beat for Katy Perry’s new song “E.T.” came from an unlikely place. The pop star told MTV News’ Sway that the producers, Dr. Luke, Max Martin and Ammo, has actually intended for the beat to be used by Three 6 Mafia, and that she’s glad she took it because “it really worked out perfectly” for what she was going for with the song.
