Voting for the 2009 Top 100 DJs Poll will be open on Aug. 3.

Votes for the top five DJs of the past 12 months (in order of preference) can be submitted at until Sept. 23.

The annual poll draws over 350,000 votes from around the world -- last year 167 countries -- and organizers are expecting the number to climb again this year.

Armin van Buuren has held the title for the last three years, a feat only previously attained by fellow Dutch DJ Tiesto.

The poll is run by and powered by music download service, the latter offering each voter a free download from its catalog of 350,000 titles.
