If you've been paying attention to the iTunes singles charts lately, you might have seen the song "Set The Fire To The Third Bar" by Snow Patrol & Martha Wainwright coming out of nowhere to move into the Top 20. The song is a good 3-4 years old - it came out on the same album as "Chasing Cars" (Eyes Open), which was released in 2006.
After being used in the Dear John trailer, the song's sales skyrocketed. And since it was never released as a single in the U.S., I've gotta believe that it's all from people seeing the trailer and going "What is that song? I must have it." Ahem. Guilty as charged; I bought it the first time I saw the trailer.
