Don’t be fooled by the romantic, easygoing orchestrations of José José’s love songs: This beloved Mexican singer and actor was an archaeologist of the human heart and the complex passions that govern our lives. He parses the difference between mere desire and true love in “Amar y Querer” and crafts a magnificent, emphatic ode to loving someone no matter what they’ve done in “Desesperado.” People in love are crazy, and he captures every nuance.
