Voted number one song of the year (it actually came out in October 2010 but who cares?), this will either annoy or delight you ( I think I know which camp Span will fall into!). For me it's a classic sound of summer and I love the way it's been used in this video. Of course being such an ear worm its found its way during the year into everything from MOTD to the Impressionists Show and anything in between (possibly even the Inbetweeners) where the word 'Hello' needed musical confirmation. Anyway 40 million (yes that's right) viewings on youtube can't be all wrong surely?
