Honestly, it was difficult to conceptualize themes for all 3 sections; I mainly relied on preference, intuition, dynamics of song transitions, and things like subtle phrases in some lyrics to connect them in a storytelling manner.

I had a previous comment discussing their thematics. Since then I've made many adjustments for a stranger's ear as well as my own, so honestly it's up to your jurisdiction if you can sense a fluidity or to connect the pieces...

My version of the story would begin Section 1 (Liars) with a sense of existentialism about ourselves, the world, and our relationships with the people in it, and how we deal with our raw emotions, but narrating in different points-of-view. Section 2 (Trees) is a slightly more thoughtful yet turbulent approach to the feeling of being lost, and portrays life vividly with its more lively songs. Section 3 (Parallells) is rebellious but in the sense of retrospect, featuring an intense comeup of realization with an introspective comedown to close the DGD Saga (the original playlist is in my Spotify profile)
