TikTok officially launched its music distribution and marketing platform, SoundOn, on Wednesday, after reportedly beginning beta testing last fall. The platform allows users to upload their music directly to platforms like TikTok, Apple Music, Deezer, and Spotify. In its first year, transaction fees will be waived for users, with SoundOn taking a 10% cut beginning in its second year of operations. Musicians will retain all rights and royalties of their music indefinitely and SoundOn will provide users with promotion, audience-insight, and development tools. [CNET]
