It's all change once again in the Irish Singles Chart as Katy Perry returns to the top of the mountain with 'Roar', knocking the legendary Finbar Furey and his 'The Last Great Love Song' down to third place in the process.

That shift means Avicii moves up to #2 with 'Wake Me Up' while Ellie Goulding holds firm in fourth spot with 'Burn'. Rounding out the top five is 'Counting Stars' by OneRepublic.

Elsewhere, it's top ten placings for Macklemore & Ryan Lewis, Lana Del Rey, One Direction, Imagine Dragons and Miley Cyrus.
