Look at "Running Up That Hill": TikTok clips existed, but the real explosion came from a TV sync, then streaming and radio. I'll grant my opponent's Astronaut example: the app can ignite a stalled song. But igniting isn't deciding, because the industry still has to convert that spark into a hit. If a track trends on TikTok and radio and playlists pass, it usually stalls. The other side's "downstream reacts" point proves coordination, not authorship: labels use TikTok as a demand signal, then make the call. Necessary spark, rarely sufficient. That's influence, not final say.
