This round of our battle for the Greatest Summer Song pits the Beatles classic "Here Comes the Sun" against Don Henley's anthem of '80s disillusionment "The Boys of Summer" — and your votes determine who wins.

After starting with 32 of classic rock’s best summertime songs last week, we’re now down to 16 for the second round. Over the next four weeks the field will be repeatedly cut in half by your votes until we arrive at the greatest summer song ever made.

The Beatles made quick work of the Who in the opening round, polishing off their competitor's cover of "Summertime Blues" with a cool 61 percent of the vote. That's impressive, but Henley had an even easier time with his first-round opponent, demolishing Metallica's "Lords of Summer" to the tune of a 73 percent beating. Now, these two classic cuts face each other for the right to move on to the next round.

"The Boys of Summer" wasn't Henley's first solo hit, but it definitely helped shift his post-Eagles career into higher gear when he released it as the leadoff single from his Building the Perfect Beast LP in 1984: A Top Five single, it helped propel the album to multi-platinum status and set the stage for the even greater triumph he'd enjoy with The End of the Innocence in 1989. "Here Comes the Sun," on the other hand, was never released as a single at all, but George Harrison's hopeful Abbey Road anthem never needed its own official 45 to achieve classic rock mainstay status.

So which one will earn a trip to the next round? Listen to both below and make your call. You can vote once per hour in each of the current Greatest Summer Song battles until voting closes on Monday, Aug. 3 at 11:59 PM ET. Your choice for the Greatest Summer Song of all time will be revealed on Aug. 25, 2015.
