Armin van Buuren, OON (born in Leiden, The Netherlands on 25 December 1976) is a Dutch trance producer and DJ. In 2007, 2008, 2009 and 2010 he was voted number one in DJ Magazine's annual top 100 list of the most popular DJs. In the 2011 list, he ranked in second place. Since 2001, Van Buuren has hosted a weekly radio show called A State of Trance, which claims to have around 15Â million weekly listeners in 26 countries; this would make it one of the most listened-to radio shows in the world. His 2008 studio album, Imagine, entered the Dutch album chart at #1, a first for a dance artist in Dutch music history. Since the release of Imagine, Van Buuren has been working with Benno de Goeij and DJ-RA of Rank 1 on solo productions and remixes. He is well known for his annual "Year Mix" which incorporates clips and custom mashups from the year's most popular trance tracks. Each year-mix consists of about 85 individual releases, edited into a two hour mix which is released on double CD as well as aired on his weekly radio show at the end of each year. According to Van Buuren, each year-mix takes several months to make, including thousands of digital audio edits and hundreds of audio plugins.
