Its music ambitions could ruffle feathers at record labels and publishers — unless it pays out. TikTok's app regularly sparks trends that help songs go viral, making it a favorite of marketers at major labels and independents. TikTok works closely with record labels and artists on promotional efforts like livestreamed concerts, in-person performances, and private listening parties with TikTok stars. Spotify has maintained a tenuous relationship with the labels over the years as it's sought to balance profit margins while splitting revenue with artists, labels, and publishers. Still, even as record labels and publishers push TikTok to pay more to music rights holders, they're investing more in the app.
