As the battle over Kesha's music career roars on, the music industry must decide how to approach its relationship with Dr. Luke. If a lesser-known or less successful producer and songwriter faced the allegations Dr. Luke does, his career would likely be over. But the thing about Dr. Luke, born Lukasz Gottwald, is that he's incredibly good at what he does. Remember, Kesha isn't up against a no-name DJ, but a person with serious clout in the industry...which may be her lawsuit's biggest hurdle—and why it is so important. He makes chart-topping hits for some of the biggest pop stars in the world, and thus makes his employers at Sony tons of money. So as we face the very real possibility that some of our most beloved songs by some of our most beloved stars may have been created by a sexual predator, we thought it would be worthwhile to take a look back at some of those everlasting songs through a slightly different lens. While the discussion to either erase these songs or relinquish our enjoyment of them varies from person to person, their glassy sheen has now, well, been dulled.
