Gina G is definitely the first one that springs to mind; such an iconic 90's song and definitely one that had a big impact, also outside of Eurovision.

 

Imaani's entry is still so good as well and another one of my favourites. Love Precious' Say It Again (deserved more) and justice for Javine. I was obsessed with Touch My Fire.

I think with Gina G have the people associate or know it was a Eurovision song and others dont and just think it was a huge pop hit. Gina G was probbaly a few years ahead of her time, i think in televoting years she would have done better, same could be said for Love City Groove in 95.
