MGMT's Time to Pretend has been voted track of the year by readers of music industry staple CMU Daily.
It saw off a close challenge from Florence And The Machine's Dog Days Are Over, which had posed a serious challenge despite only being released on November 30th.
Third place went to One Day Like This, the anthemic climax of Mercury Music Prize-winning album The Seldom Seen Kid.
Fascination by Alphabeat was fourth while Glasvegas' Geraldine rounded off the top five.
CMU editor Chris Cooke commented: "Despite the challenges currently facing the music industry, this year's CMU track of the year poll proves that new music is still as fresh and exciting as ever.
"All the artists in the top five have really captured the public's imagination in different ways in 2008."
Maureen Kenny of Columbia Records, who signed MGMT in New York, said Time to Pretend was a "special song" and the reason she snapped the band up.
Speaking of the song, she added: "It seems to have turned into an anthem this summer. I never dreamed it would go this far, but I'm really pleased."
