There are two for me.

For the life of me, I can't remember what the first song is called. It's a sort of African, or Carribbean. Lots of chanting, and steel drums. It's the kind of song that sticks in your head long after you hear it. It has with me.

The second is Xpander Edit, by Sasha. I don't know why, but it moves me so. Makes me think of stars and champagne...
