I think was going to be a single when the E.P. first came out, but they probably changed their minds when they thought that they had already released five singles last year. I don't think Lost! or Lovers in Japan were as successful as they could've been because they were constantly competing with Viva la Vida and Violet Hill for radio play.
well for me it's like the verses are ok but the chours is the best!...i really enjoy it it's something you wanna listen to allmost all the time...so if they would have changed the verses a little it would've been greater i think..but that's just my opinion but still it's a great song!!
