I seldom do one of these posts on Saturday morning. Mostly because the Late-Night TV Music gods seldom dish up anything on Friday night that’s worth writing about — like, say, The War on Drugs debuting their new song Ocean of Darkness on The Tonight Show Starring Jimmy Fallon. That alone makes it worthwhile. Of course, if you happen to be a K-pop fan, you might prefer SuperM’s performance of One (Monster & Infinity) on The Late Late Show With James Corden. I’m not judging. Not today, anyway. Another rarity.
