This song provided the backdrop to much of my time in the UK.
I ADORE it and would defy anyone not to want to dance around the room to it.
I once saw some buskers in Galway have a stab at it (and do a bloody great job, even if they did need a good wash).
Now I've finally made peace with the evil empire of Apple, this song accompanies me on my daily journey to work and on solitary runs around the bays.
Jessie J rocks. Fact.
