With the first round of Ultimate Classic Rock's Greatest Summer Song ending tonight, we thought we'd take a look at where the voting stands. We've also embedded all of the 16 polls below so that you can help make sure your favorite songs advance to the second round.

A couple of the races are very tight. Bryan Adams' "Summer of '69" holds a slight 52-48 percent edge over Van Halen's "Beautiful Girls" in our closest race, while "Hot in the City" by Billy Idol is beating Jimi Hendrix's "Long Hot Summer Night" by a slightly more comfortable margin of 55-45 percent.

Don't let some seemingly large leads fool you into thinking the rest of these battles are over. For example, Mungo Jerry's "In the Summertime" has a 58-42 lead over the Ramones' "Rockaway Beach." The Kinks' "Sunny Afternoon" and Meat Loaf’s "You Took the Words Right Out of My Mouth" both have 20 point leads -- 60 to 40 percent -- over, respectively, the Lovin Spoonful's "Summer in the City" and Judas Priest's "Wild Nights, Hot and Crazy Days." But as we've seen in previous polls, a surge in the voting in the last few hours can easily change the outcome.

Remember, you have until 11:59PM tonight (July 27) to vote in the first round of the Greatest Summer Song battle. You can vote once per hour in each contest in the poll widgets below. The second round will begin tomorrow, and your choice for the Greatest Summer Song of all time will be revealed on Aug. 25, 2015.
