> I think you are looking for elvis costellos- 'whats so funny about peace love and understanding'.I know it is in one commercial for that movie that I saw. I am a big elvis costello fan and I know that this is featured in atleast one of the commercials.
---Depending on the spot, there are a few songs in the 'Lost in Translation' trailer. One is Elvis Costello's 'What's So Funny About Peace Love & Understanding.' The other is 'Just Like Honey' by Jesus & Mary Chain. Both are on the soundtrack.
