Summer doesn't OFFICIALLY begin until June 20 (and we know that because we consulted the Farmer's Almanac for the very first time and probably last in our entire lives), but that doesn't mean you haven't started dressing, slacking off and/or partying like summer's fully here. Accordingly, you need the ultimate summer jam -- the one singular seasonal jam that will forever seal the summer of 2012 in your soul (and mix CD).

We teamed up with our friends at Seventeen magazine and picked five of the songs we think will rule the summer. But like with all things superlative and all favorite songs, there can only be one that trumps them all. Check out our five top summer song picks below, and vote for your favorite in our poll. We'll announce the winner on Wednesday, May 30.

Walk the Moon, "Anna Sun"
