Delivered by a voice with harmonic lyrical phrasing and contemporary crooning, Perry’s lyrical capabilities range from metaphoric calls for love to poetic searches of self-expression. 4 A.M. Nostalgia establishes a narrative that reveals a delicate perspective on the complicated nature of both being in love and what love is in itself. In what seems to be a display of vulnerability to some, his music reiterates the timeless battle between love’s beauty and its toxicity.
