A jingling keyboard, courtesy of Eddie Kendricks's "Intimate Friends," is a fine thing on which to base a song; TV-as-lovespeak wordplay ("Stay tuned!" "Technical difficulties!") is not. A creepily gleeful Alicia Keys does both on the pretentious "Unbreakable," unconvincingly casting herself as a nonceleb who mulls over modeling her relationship after unstable star couples like Joseph and Katherine Jackson and Ike and Tina Turner. Why not Bobby and Whitney too?
