Algorithms Replace Radio

In the pre-streaming era, a song needed radio play, MTV rotation, or retail shelf space to reach mass audiences. Today, TikTok's recommendation algorithm has become one of the most powerful forces in music discovery. A 15-second clip set to an unknown track can rack up millions of views in days, and the song's Spotify streams follow almost instantly.

TikTok's algorithm does not care about label budgets or artist fame. It optimizes for engagement signals — watch time, replays, shares, and video creation using the sound. This means a bedroom producer in Lagos can go viral as easily as a major-label artist in Los Angeles.
