What exactly is "a TikTok-affiliated agency"? Because to me it sounds just like a publishing label that takes a massive cut between the actual content producer (tiktok user) and the platform (TikTok). If that's the case, that's just another situation just like what happened between Spotify and the artists. I heard a lot of noise about it, but turns out Spotify only takes a 30% cut. Why do artists complain about their 70% cut? Oh, that's because artists signed to a label only get a fraction for it, while their label gets the rest. That has nothing to do with Spotify and all with contracts between artists and labels. None of that applies to independent artists with no label, who all get their full 70%. Is "a TikTok-affiliated agency" basically acting as a music label here?
