Calvin Harris had five UK number-one singles before releasing “Summer” in 2014. They were “Dance Wiv Me” with Dizzee Rascal and Chrome, “I’m Not Alone,” “We Found Love” with Rihanna, “Sweet Nothing” with Florence Welch, and “Under Control” with Alesso and Hurts vocalist Theo Hutchcraft.
“Summer” became his sixth track to reach the top of the UK Singles Chart and was notable because Harris both wrote, produced, and performed the song’s vocals. It was released in March 2014 and topped the chart in May.
A common mix-up comes from counting songs Harris wrote or produced for other artists, such as Cheryl’s “Call My Name” or his remix of Florence + the Machine’s “Spectrum.” Those tracks reached number one but were not generally counted among his credited artist singles in this quiz’s tally. Counting credited number-one singles gives five before “Summer.”
