For fans of R&B ballads, the supersized emotions, frequent vocal gymnastics, and production maximalism can seem to be the most direct window to the artists’ inner life, revealing some deeper vulnerability or emotional longings that the more uptempo tracks generally ignore. Beyoncé, being Beyoncé, does this better than most. This Spotify playlist, from KH Bionic Chiu, is one in a series of pop star ballad playlists. The track selection is solid, even if there’s very real rhythm to the selections and the inclusion of the Luther Vandross so close to the top of the list is a curveball. Usually these type of playlist front-load the hits and get around to the collaborations, and, here, a track like “Best Thing I Never Had” doesn’t appear until we’re over a dozen tracks into the playlist. -- Sam Chennault
