Frontman Matt Healy described his lyrics for The 1975's self-titled debut LP to The Guardian as "a genuine kind of diary." He added: "And that's the thing I'm really proud of in this album – it's me figuring myself out. Even the line in Heart Out – 'Your obsession with rocks and brown. And fu--ing the whole town' … I'm always talking about me, really."
Bruce Springsteen wrote "Blinded By The Light," which was a #1 hit for Manfred Mann's Earth Band. The "Madman Drummers" line is a reference to Springsteen's first E-Street drummer, Vinnie "Mad dog" Lopez.
