It's not hard to understand why Hardwell would be on this list. Hopefully you were at the Ultra Music Festival this past March, or at least watching the live stream; did you happen to catch the set that Hardwell threw down?! It's part of the reason why EDM is getting so popular... DJs know how to connect with the crowd. He put on a clinic, and unanimously won that first weekend. Add onto that his weekly "Hardwell On Air" show, which has been going strong for the last few years. He's smashing up any venue he hits, and most importantly doing it all with a smile. It's almost hard to believe he only got his start in 2009!
