“Once, long ago, a friend described the act of driving with the windows down while still blasting the air conditioning as ‘Peanut Butter Jelly'," Morby explains of the song. "She told me this phrase was common where she came from but no one I’ve ever talked to has said the same nor can I find anything about it online. But I always loved the phrase and have used it ever since. I also love a peanut butter and jelly sandwich (and all its variations) and so this is a very fun song for me. An end of summer song. Listen to it with the windows down…and the air conditioning up."

“We’ve taken this opportunity to collaborate with a handful of my favorite businesses around the country to have some fun and make some delicious meals, snacks, and drinks in celebration of the single," he continues. "All are a play off of one of the most timeless recipes ever.”
