New Jersey-born Jax charged through Season 14 of American Idol with rock-star bravado and soulful vocals. Wrenching ballads like the twinkling piano lament “Stars” and the vengeful “Wrong Girl” are squarely in Jax’s Idol wheelhouse, but her first EP after the show’s run also displays her cutting wit and genre range. “Kickin’ and Screamin’” is a jittery, club-ready cut that shows off the lightness in her voice, while the gimlet-eyed title track is a cutting rebuke aimed at failed pickup artists.
