- Azerbaijan: Farid Mammadov - Hold Me
2011 winners Azerbaijan are pinning their hopes on Farid Mammadov who will be singing the romantic ballad "Hold Me".
- Finland: Krista Siegfrids - Marry Me
Krista Siegfrids is representing Finland with "Marry Me", a song which she says is a protest against a decision by the country's government to vote against gay marriage legislation.
She told the Independent: "I don't think 'Marry Me' is political, it's about love and tolerance. But gay marriage is not allowed in Finland and that's wrong. I wanted to make a statement about that."
Organisers of the contest, have forbidden "lyrics, speeches, gestures of a political or similar nature", but it seems this song has flown under their radar.
