Day 9 - an entry that you didn't like at first but now like.
It was hard to choose a single song. There are always songs in every contest that I didn't like at first and now like! However, I think this has the largest gap of how much I hated it at the time of the contest for it's boringness to how much I really love it now!
Edit - also check out the english version in pixielix's comment - I think it's lovely in English too!
