The Scottish DJ who goes by the name of Calvin Harris has become very popular over the past year or two, penning such hits as Rihanna's 'We Found Love' and 'Let's Go' with Ne-Yo. Calvin is one of the biggest producers out there right now because of his great dance hits, and now he is readying the release of the fifth single off his upcoming third album. The single features Florence Welch of Florence + The Machine and it is quite a pairing. I never expected Florence to take a stab at dance music, but it works surprisingly well. Her voice is one of the most beautiful I have ever heard, and in 'Sweet Nothing' it flows beautifully over the beat Calvin Harris has crafted. Florence on this track sort of feels like Sia on 'Titanium': it's an unlikely pairing that blows you away. I love seeing artists take risks, and Florence's risk paid off.
