Van Halen's "Summer Nights" lines up against "Feel Good Hit of the Summer" by Queens of the Stone Age in the first round of our Greatest Summer Song battle – and your votes determine the winner.

We've selected 32 of classic rock's best summertime songs, and paired them off in 16 first-round duels. Over the next five weeks the field will be repeatedly cut in half by your votes, until we arrive at the greatest summer song of all time.

You'll notice this is one of two Van Halen songs in our bracket, with the band's David Lee Roth-era "Beautiful Girls" currently facing off against "Summer of '69" by Bryan Adams. Even just choosing from the Sammy Hagar days was tough, but in the end, this tale of a hot summer night from 1986's 5150 claimed victory over "Cabo Wabo."

Now the question is, how will it do against some fierce and relatively young competition? In this case, the challenge comes in the form of Queens of the Stone Age's hypnotically repetitive ode to "nicotine, valium, vicodin, marijuana, ecstasy and alcohol" from their 2000 album Rated R. Josh Homme and company have an ace of their sleeve in this battle, too. Listen closely towards the end of this song and you'll notice none other than Rob Halford of Judas Priest helping out with backing vocals.

So who gets to move onto the second round? You can vote once per hour in each of the 16 first-round battles until voting closes on July 27 at 11:59 PM ET. Your choice for the Greatest Summer Song of all time will be revealed on Aug. 25, 2015.
