Owl City is top of the UK singles charts with his debut single called 'Fireflies', which has previously topped the charts in both the USA and Australia.
Fireflies overtakes former number one 'Replay' by Lyaz and easily holds off the week's highest new entry from Example with 'Wont Go Quietly' at number 6.
There is no change in the top two positions in the album charts with Florence and The Machine's 'Lungs' at number one and Paolo Nutini's 'Sunny Side Up' at number 2. 'The Betrayed' by the Lostprophets is the week's highest new entry at number 3.
