The Eurovision Song Contest housed a handful of already-established acts across its history.
It can be difficult for artists to evaluate whether or not risking their career reputation is worth it. Eurovision opens its arms to anyone who wants to compete, regardless of their already established impact on the industry, which has allowed some global superstars to take part.
The contest platforms hundreds of musicians every year but some heavyweights throw their hats into the ring to test their mettle against the newcomers. While the likes of ABBA originated their fame in Eurovision, some stars chose to dive in right at the peak of their popularity.
