Williams' success in the past year and a half has been staggering, overall he has earned three U.K. No.1 songs with 'Happy,' 'Blurred Lines' and 'Get Lucky,' which also are all part of the UK's 10 best-selling downloads of all time. Furthermore, all three tracks sold over 1 million copies within a year of being released, an achievement only reached once in Britian before, and that was by The Beatles.

He continued, "The people of the UK have been so supportive of me over the years, allowing me to be an artist and allowing me to work with other people and supporting what it is that I do. That's the lifeline, without them you're just a musician with a couple of ideas but with them, that is the thing that changes everything when they get involved, your little idea can become something, so .thank you!''
