This week, Calvin Harris reminds us all why he is one of the world's most in-demand producers with his latest floor filler, fittingly entitled 'Summer', going straight in at No. 1.

Harris' domination of the chart means soulful piano-man, John Legend, drops from the top spot down into second position with his typically tear-jerking ballad 'All of Me'. Rounding out the Top 3 is Sigma's 'Nobody to Love', having moved all the way up from No.9.

Irishman Hozier drops from number two into fourth position and the biggest climber this week comes courtesy of Dutchman Mr. Probz's 'Waves' which leaps from No. 22 to No. 7 due in no small part to the success of a recent remix of the track by Robin Schulz.

With the chart as a whole taking on a considerably more dance-y complexion, it would seem people are starting to gear themselves up for the festival season...
