Martin Garrix, Hardwell, Avicii and Dimitri Vegas & Like Mike all feature - but who took the top spot?
The veteran Canadian DJ is down 9 spaces from last year's list.
Despite a the release of their new album this year, the Australian twin duo have slipped down the by list 3 places.
It has been an eventful year for the Indian-American DJ, who is catapulted all the way to number 23 on our list.
After the release of his album 'True Colours" this year, the German-born artist retains his spot on the list for another year.
Up two on last years rankings, the future is only getting brighter for the Dutch-Morrocan.
Collaborations with Madonna, Skrillex and others have made 2015 a busy year for the Mississippi-born DJ.
In 2015 the Dutch duo have collaborated most notably with Carly Rae Jepson and Armin Van Buuren, and continue to be hugely popular.
Romero's remix of One Direction's '18' is perhaps his most famous work of 2015, and the Dutch artist's career continues to gain success.
The highest ranked collaboration on the list, the two Swedes have enjoyed a massively successful 12 months, in particular their hit 'Sun in Shining' in June.
The two Canadian brothers continue to win fans with their house music stylings, achieving the coveted number one stop in the UK charts for their remix of Tinie Tempah's 'Tsunami (jump)'.
The Dutch-born artist continues to delight fans with his unique sound, falling just one point in this years rankings.
Another Dutch-born DJ pair, W&W have gone from strength to strength since their debut in 2008. No doubt the future is looking like more success for these two!
2015 saw the release of the Swedish-born DJs debut album 'Forever' on Def Jam Recordings, and with it, his position on the house music scene cemented.
With a huge 22 point jump in the ranking, the Dutch-born DJ has evidently found his niche. At only 20 years old, Heldens' undoubtedly still has his best years of music ahead of him.
This year has seen Harris, one of the most recognisable DJs in the world, become the highest paid DJ in the world. The Scottish-born artist has had an unbelievable year, and his success shows no signs of waining.
After another busy year, the Florida-native continues to remain popular amongst electro-house fans, and has become and increasingly recognisable face in the public eye.
One of the most recognisable faces and styles on our list, the Californian has retained his status as a top 10 DJ. At #9, he's also the highest ranking dubstep DJ on the list.
Another Dutchman, Afrojack continues to climb the list and gain followers with each new project he works on.
The 26 year old Swede has made an impressive impact on the electronic scene in a relatively short space of time. With his new album now completed, we fully expect to see Avicii in the list again next year.
Perhaps the most well-known DJ on the list, Guetta is still gaining momentum, up one place on last years rankings. The French-born artist is likely to feature in the top 50 until he retires!
A true veteran of the game, the Dutch-born trance legend continues to innovate and expand his horizons, whilst somehow keeping his fiercely loyal fanbase.
Another true veteran of the game, and another Dutchman, much like Tiesto, Van Buuren's success continues to expand. With recent award nominations, and a new album out October 29th, Van Buuren's commercial success shows no signs of slowing down.
At just 19 years old, this Dutch DJ's explosive career is still going just one way; up.
Still immensely popular, and with his first studio album, 'United We Are', out this year, this year sees Hardwell drop one place after two years at the top of the list.
From Belgian and Greek origins, these wildly popular two brothers has undoubtedly taken the scene by storm. Congratulations gentleman!
