This is one of my favorite songs and videos ever. I love the dinner party-- the dancing, the food and guests all seem genuine and fun. I want to be there. Without knowing the lyrics, we know what this song is about. He's singing, "You are a super hot lady, and if I was a younger guy, I'd be flirting like crazy with you. Your boyfriend over there is a doofus for being angry and is totally missing the point of life." Then in the middle (03:54), the song changes and Farid does a serious and soulful breakdown. The song is now about every romance that has ever happened or will happen on the face of the earth. It is so beautiful Farid can barely stand it (05:22), but the dinner party crowd is drunk and luckily their cheering gets him out of that deliciously wistful serious place.
