Jonas Brothers, Juice WRLD and Ariana Grande already have bids for summer supremacy -- but don't count out upcoming tracks from Billie Eilish and BTS.

It’s still cold out; in some parts of the country, there’s still snow on the ground. We haven’t even gotten to springtime yet! So why are we already talking about the Song of the Summer race?   

Because the most ubiquitous songs of each summer season -- the ones that we hear over and over, on portable speakers at the beach and on every barbecue playlist -- typically take a few months to catch on, contenders for the top of Billboard’s annual Songs of the Summer chart are often released well before summer starts, and sometimes even before spring starts.   

  

The original version of “Despacito,” the Luis Fonsi and Daddy Yankee smash that topped the 2017 Song of the Summer chart, was released in January of that year. Other recent Songs of the Summer, from Drake’s “One Dance” to Iggy Azalea’s “Fancy” to Carly Rae Jepsen’s “Call Me Maybe,” were issued months before the official chart got going around Memorial Day in their respective calendar years.While we won’t what the official 2019 Song of the Summer will be for nearly six months, there’s a pretty solid chance that we’ve already heard it.  

So which songs that we know about are worth keeping an eye on, as major contenders or as outside shots? And which artists could very well impact the Song of the Summer race before we even hear their new tunes? Here’s a way-too-early breakdown of a 2019 Song of the Summer race that’s still brewing -- and contains a ton of fascinating competitors:
