The #1 DJ on the djmag.com 100 list is Armin van Buuren. He has held the spot since 2007. Armin hosts a popular podcast called A State of Trance. Most recently, #1 DJ has produced an artist album called Mirage. The album is highly collaborative (which is something I love to see). For example the song below "Youtopia" features Adam Young of Owl City. It is a relatively calm song especially with Young's vocals, and shows AvB's ability to be dynamic.
Below also is "Orbion" a track I consider underplayed off of the Mirage album. The intro and semi-vocals are alright, but the song picks up in a huge way later on. Armin doesn't let down and I think he has earned the title, but there are a lot of up and coming DJs that will be keeping him on his toes.
