That figure works "by the pale dull pallor of an old gas [?] light" in a place found "down on Lenox Avenue". Its central figure "sleeps like a rock or a man that's dead" after  singing a song "far into the night" that causes the stars and moon to go out. In that song, that figure notes that he has this poem's title affliction, and "can't be satisfied". The namesake of a 1926 collection that also included its author's poems "Mother to Sun" and "The Negro Speaks of Rivers", for 10 points, identify this work that opens by describing a "drowsy syncopated tune", a poem about a Harlem piano player by Langston Hughes.
