Here is the REAL Lovers In Japan in acoustic. I am guessing that the song that appeared on Greys Anatomy is something different. This makes it 6 out of 10 songs have already been released. Violet Hill, Viva la Vida, Life In Technicolour, Lovers In Japan, Lost and which ever song appeared on Greys Anatomy.
