Katy Perry has taken the top spot in the UK Charts this week with her new track Roar after Ellie Goulding held the top spot for three weeks. Burn stayed at the top giving Ellie Goulding her first ever top spot on the UK charts in her career, and it was short lived. Roar has become the third fastest selling single of this year so far, bringing Katy Perry right to the top spot. Katy has done the same thing over in the US too after knocking Robin Thicke off the top spot of the US singles charts. He maintained his top spot for a whole 12 weeks with Blurred Lines, a song that has become incredibly popular over the past few months. Ellie Goulding now sits in 2nd place.
