TikTok's Add to Music App, previously available in a starter-kit of 21 countries including the U.S. and U.K., has been expanded to 150+ countries. The feature allows users to save the songs they discover on TikTok to Amazon Music, Apple Music or Spotify, subject to local availability.

Said Isaac Bess, TikTok's global head of distribution partnerships, "With the Add to Music App, we're streamlining the music-discovery experience for both TikTok users and artists. We're really excited to be bringing the feature to millions more music fans around the world, providing even more opportunities for music discovery and consumption, and for artists to reach new audiences and grow their careers."
