“My happiness is a long shot,” sings Jillian Jacqueline on “Somebody,” the closing track of Side B. The rest of the EP, a follow-up to 2017’s Side A, is just as gloriously straightforward, as she addresses heartbreak on the gorgeous acoustic “Sad Girls” and the bad decisions we make in the wake of it all (“got a credit card, couldn’t pay it off”) on “Tragic,” before offering an infectious, danceable reminder to focus on what matters with “Priorities.” Jacqueline’s able to meld downright melancholy concepts (“when did the future get so damn important when we could die at any time?” she asks on “Priorities”) with enough bursts of joy to make pondering the bad stuff a whole lot less painful.
