"Say My Name", recorded by Porter Robinson, is a song featured in the Person of Interest episode “Masquerade”. It is played in the club where Sofia Campos goes looking for her friend Gabi.
"Say My Name" is one of the few songs that is source music (sometimes called diegetic music). Unlike the episode's score, source music is heard by the characters in an episode and originates within the story itself.
Say my name and you can say it with honor (x?)
