Hello anon! As far as I know, a full version of “Fallin Fallen” has not been made available yet. It has been receiving a lot of attention lately, though, so it’s entirely possible that it will be released in the future.
Hope that helps, anon. Stay excellent!
P.S. for those who don’t know, “Fallin Fallen” is a track from the soundtrack of the film Getting Go, the Go Doc Project (which is interesting, and I mean that in a good way). It also features s/he’s “One To Glow” and “Here With You.” You can check it out on Netflix or stream it here (for $3.99 in the US). You can also learn more about the project by checking out their Facebook page.
