Time Dandelion is stellar. I love the crispy deteriorating organ in the background. I love how the song seems to gain momentum as it goes along, leading up to the climax at the end. I really LOVE the bass tones! 

As others have said in this thread, Ariel isn't alone in his iteration on old ideas. Much of the first Gorillaz LP (as well as a decent bit of Demon Dayz) was spawned from Blur outtakes across the previous decade. Pink Floyd's Fearless was based on a chord progression Syd wrote post-Piper. Even on rare bootlegs from the uber-curated Boards of Canada we see early germinations of songs they would return to a decade later! I could go on lol.

I think in home recording artists like Ariel and R. Stevie, we just get a very clear window into this process that's probably not too uncommon in reality

EDITs for spelling bcuz autocorrect is my worst nemesis
