Nobody knows how to do misery the way they did in the ’50s and ’60s. Part of it is that it wasn’t as culturally acceptable, especially for men. But in the absence of being able to vent feelings in public, or with friends and family, the artists here turned to the miniature melancholies of pop, imbuing simple songs with almost operatic heft. We update picks here regularly. If something pulls at those heartstrings, add it to your library.
