"We Are The People" - Empire of the Sun.
A song which my mum calls "beyond brilliant", and I think that's just the perfect way to describe it.
This band may have figured in many of the "big in 2009" lists but they maybe didn't grab the public's attention as much as some of the more overrated acts which too much newsprint/web space was wasted on; nevertheless they broke through the wall and into the UK top 20 singles chart. It was pretty amazing that something so good could actually become a hit in this country, and briefly gave me some hope that good music can prevail.
"We Are The People" has a floaty, dream-like quality and a memorable chorus. During the year it persistently battled with "Standing on the Shore" for absolute-favourite-status and my 3rd/4th chart placings were frequently switched round: in the end though, this was the undisputed winner of that battle.
