• The 1975 frontman Matthew Healy was brought in to write a song for Four after the 1D quintet said they really liked his band. However, he left the session wondering why he was asked to contribute. "They didn't seem to be actually that interested; they just wanted to play me this song that they said was really, really inspired by us," Healy remembered to Spin.
  
  The song in question was "Change Your Ticket," whose groove sounded just like the 1975's "Girls." Healy asked that the group not make his influence quite so obvious: "'Listen guys, fill your boots, the song doesn't sound that much like 'Girls,'" he said. "But the guitar and the whole vibe of it is a complete lift. So take the guitars off, and we're good."
  
  According to Healy, 1D agreed to change things up, but an unaltered version of the song did land on Four's deluxe edition. The 1975 frontman was annoyed as the group failed to clarify that he didn't help write it, even though he wasn't actually credited. "It would have been a bad 1975 song," Healy explained.
