According to Mark Savage from BBC Music, "Perfect Illusion" is a disco-rock song, which is composed around a building chord sequence, which he felt leads to a "compelling sense of urgency". The singer's vocals are kept raw and untreated on the song, eschewing autotune.[53] The composition consists of "pulsing verses" and a guitar-and-vocal breakdown before the final chorus, with Gaga singing the main title multiple times. Around the two minute mark, there is a key change for the final chorus.[54] In "Million Reasons" Gaga talks about love which does not last, with the singer uttering the title in several variations on the verses.[51] The composition consists of simple country-oriented piano and guitar instrumentation.
