Empire of the Sun: Walking on a Dream - Took 7 years to become a hit in the U.S. because it was ignored during it's original release. Honda commercial gave it a second run.
I was listening to that song like every day in summer 2012 and forgot about it and then it began smashing in the US and then it was released and smashed in the UK in summer 2013
I don't get why they didn't release it in the UK in 2012, it was receiving so much attention from the advert it was featured on.
