Singer-songwriter Cody Fry was riding high. His song "Things You Said," a duet with Abby Cates, was exploding on Douyin, the Chinese version of TikTok, racking up over 750,000 videos in a single day. Then, the music stopped. On Thursday, Universal Music Group (UMG), the world's largest music company, pulled its catalog from TikTok, effectively muting millions of fan-made videos featuring UMG artists like Fry, SZA, Taylor Swift, and Ice Spice.
