Social media hasn’t just changed how we communicate, but also what we listen to and how we hear it. With that, here’s our up-to-the-minute playlist of tracks making the leap from your social channels into the broader cultural stream. On top now is Megan Moroney’s “6 Months Later,” a familiar story to anyone who’s been dumped. “It’s a tale as old as time, I guess/When you couldn’t care more, I couldn’t care less/You’re a little too late to the party, heartbreaker/What doesn’t kill you calls you six months later,” she snarks, mocking her former paramour’s second thoughts. Because there’s no schedule for going viral, our editors update these selections throughout the week as needed, so if you hear something you want to hang on to, add it to your library. If it’s trending there, you’ll hear it here.
