The Eurovision song contest is a time-honored tradition of international strategy, bizarre musical performances, and, occasionally, the chance to see the making of a superstar. It's no wonder Netflix is making a movie about it! While many of the contest's winning acts have failed to translate their wins into major successes, a handful have managed to make their mark, either in their home countries or around the world. We've rounded up some of the most successful stars who appeared on Eurovision (caveat: we're focusing on stars who competed early in their careers, not the ones who competed once they were already recognizable stars).
