Peace vocalist Harrison Koisser told NME: "It just happened over the space of 15 minutes. The lyrics sort of popped into my head so we recorded them. Sometimes it's good to keep stuff straightforward."
At 152 beats per minute, this is the fastest song on the In Love album.
Harrison Koisser said of this teenage paean to diving headfirst into your first crush: "'Lovesick' is a really uncool song. Saying that, sometimes it's not about anything except what you FEEL. And when you reach that place, things happen that are beautiful. Beautiful because they're really really real."
The song's music video was directed by Jesse Jenkins, and is a sequel to the band's previous clip for "Wraith."
"St. Elmo's Fire (Man In Motion)" was not written for the movie, but for Rick Hanson, a wheelchair athlete whose 1985 "Man In Motion" tour logged 24,856 miles on his wheelchair in 34 countries while raising $26 million for spinal cord research.
