Cross-Platform Music Discovery Integration refers to the technological framework that enables seamless music discovery and sharing across multiple streaming services and social media platforms¹. This includes features like TikTok's "Add to Music App" that allows users to save discovered songs directly to Spotify or Apple Music², and Spotify's "Share to TikTok" functionality³. The integration utilizes APIs and unified interfaces to connect disparate platforms, enabling users to discover music on one service and instantly access it on their preferred streaming platform⁴. This approach maximizes artist visibility and enhances user experience by breaking down platform silos in music consumption.
