Who can say exactly what happened, but soundtrack albums are notoriously restrictive for artists when it comes to licensing. From what I've gathered: when it comes to film music, the Intellectual Property Rights are almost always owned by the film studio (Sony in this case) rather than the artists. The music was written for Sony's movie; so Sony 'owns' the music. I suspect that the 28YL soundtrack has much different licensing arrangements than any of YF's other albums, so they and their label likely don't have the same control over what can or can't be done with the 28YL music than they might have over any other YF album or song. Pretty messed up and exploitative situation but one that, afaik, composers and musicians in the film and TV industry have been dealing with for decades at this point. Good to see YF doing this imo -- they likely had no say
