Music Streaming (e.g. Spotify)

Question

Design a music streaming application similar to Spotify, Apple Music, or YouTube Music that lets users browse and discover music, search for tracks and artists, open albums and playlists, and play audio with a persistent player and queue.

Focus on the front-end architecture and the client/server contract for browsing, playback, queue management, local persistence, and reconnect behavior. You do not need to go deep on recommendation ranking, music licensing, or the full audio ingestion and transcoding pipeline.

Real-life examples

• https://open.spotify.com
• https://music.apple.com
• https://music.youtube.com

Requirements

• Users should be able to browse or discover music, search for tracks, artists, albums, and playlists, and open collection detail pages.
• Users should be able to play music with a persistent player while navigating between different parts of the application.
• Users should be able to manage a queue while moving between different playback contexts.
• The design should consider offline and reconnect behavior where relevant.
• You do not need to cover recommendation ranking, music licensing, or the full media ingestion and transcoding pipeline.
