Zac Brown Band's newest single, "Castaway," evokes laid-back island vibes and will make listeners thirsty for Pacifico with lots of lime -- and have them pining for a tropical vacation.

"Castaway" is from ZBB's No. 1 album Jekyll + Hyde, their fourth studio project. The song begins with Brown and company singing, "Pour me another one / Make it a strong one / We're gonna have some fun tonight" -- the beginning lines of the tune's chorus -- a cappella. The island-tinged track features ukulele and pedal steel guitar that differentiate it from the group's previous singles from Jekyll + Hyde, "Homegrown," "Heavy Is the Head" and "Beautiful Drug," while the song's lightheartedness and spontaneity give fans a look at a different side of the band.

"I wanna be a castaway / And leave the world behind / Take a tropic holiday / Say goodbye to keeping time," Brown sings. "Wasting away down by the coast / Pacifico and chasing lime / Easy living down in paradise."

Zac Brown Band recently set a record with their single “Beautiful Drug": The song became their 13th tune to hit No. 1 on the Billboard Country Airplay chart, making the band the country group (three or more members) with the most career No. 1 singles on that chart.

"Castaway" will officially impact country radio on April 25. Following the group's upcoming 2016 Southern Ground Music & Food Festival, ZBB will kick off their 2016 Black out the Sun Tour on May 19.
