Pharrell Williams has scored the top-selling single of 2014 in the UK with his hit Happy.
He was followed by Clean Bandit and Jess Glynne, whose track Rather Be was not only the second best-selling single, but also the most-streamed track of the year.
According to Digital Spy, data from the BPI which represents the UK's record labels showed that the top three best sellers was rounded out by John Legend's All Of Me, with Mr Probz coming in at number four with Waves and Ed Sheeran's Thinking Out Loud at number five.
Former X Factor contestant Ella Henderson made number six with her song Ghost, Sam Smith was at seven with Stay With Me, Meghan Trainor's All About That Bass was at eight, nine was Timber from Pitbull featuring Kesha, and the top 10 was completed by George Ezra's Budapest.
Streaming of music has doubled in the last year with nearly 15 billion songs being streamed in 2014 from sources such as Spotify, Deezer and Google Play.
Pharrell's Happy, which went four times platinum in the UK, came second to Clean Bandit in the top 10 most-streamed songs of the year, while John Legend was at number three again.
Mr Probz also stuck to number four matching his sales success, but Sam Smith's Stay With Me jumped to number five and Ed Sheeran was just behind at six.
George Ezra found himself slightly further ahead in the streaming chart at number seven, Ed got a second entry this time with Sing at number eight, Pitbull and Kesha were at nine again, and just making the top 10 was Magic! with Rude.
Spotify's head of label relations for Europe Kevin Brown said: "2014 has been a year in which streaming has truly become mainstream in the UK, as proven by the billions of streams by music fans on Spotify in the UK this year.
"Wonderful British artists such as Ed Sheeran have been responsible for both a huge year of music consumption in the UK, and also generated massive quantities of streams all over the world."
