I had a revelation today and I hope nobody else has posted this because I was so proud to work it out
The album is a trinity that opens with Melodies and Desires and closes with Sleeping Alone. So the trinity opens with "I'll be the rhythm and you'll be the beat/ And love, the shoreline, where you and I meet" and closes with "Love was my shoreline / I stare myself blind". It's definitely not a coincidence, I thought using that image again was a really poignant way to close this chapter
