"Playing With Fire" - Ovi and Paula Seling.
In retrospect, my favourite Eurovision Song Contest entry from 2010. Perspex pianos at the ready for a high-energy duet with little shades of drama and "Poker Face", and I thought Ovi and Paula made a very appealing duo.

Off-topic, followers of Norway's MGP will be familiar with Ovi thanks to the very nice "Seven Seconds" from the 2009 contest. You know how much I love piano-pop so this one really appealed to me: http://www.youtube.com/watch?v=xHuxN9R-fZU and I think he's very good indeed - hope to see him representing either Romania (again) or Norway at ESC someday.
