Fans to vote for System Of A Down setlist

System Of A Down are asking their fans to submit set-list requests for their summer shows, the Nme.com reported.

They're running a competition from Systemofadown.com, with those submitting set-list requests getting the chance to win gig tickets.

"We want to know which songs you most want to hear on the road this summer," they explained.

"As a reward for telling us your top six setlist requests, one winner from each tour city will win a pair of tickets to his/her local show. They will also win a setlist from the show they attended, signed by all of us."

The contest includes System Of A Down's upcoming headline performance at the UK's Download Festival on June 11.

The band had been on hiatus since 2006 before announcing they were getting together for 2011 gigs.
