When Ingrid Michaelson was road-testing songs that eventually went on her recently released album “Human Again,” she was a bit torn.

Her 2006 album “Girls and Boys” was such a pop hit with tracks such as “Die Alone,” “Masochist” and “Breakable,” that her fans were a bit dismayed by some of her newer work. Like fans of most artists, they wanted to freeze Michaelson’s music in time.
