How to Build a Music Streaming Platform in Bubble

Create 'Artist' with: name, bio, image, genre. Create 'Album' with: title, artist, cover_image, release_date, genre. Create 'Track' with: title, album, artist, audio_file (file), duration_seconds (number), track_number (number), play_count (number). Create 'Playlist' with: name, creator (User), tracks (list of Tracks), is_public (yes/no), cover_image. Add to User: 'library_tracks' (list of Tracks), 'library_albums' (list of Albums).

Create a home page with sections: Featured albums (curated), New Releases (sorted by release_date), Top Tracks (sorted by play_count), and Browse by Genre (category buttons). Each album card shows cover image, title, and artist. Clicking an album opens a detail page showing the track list in a Repeating Group with track number, title, duration, and a play button. Add a search bar that searches across tracks, albums, and artists.

Add a Floating Group at the bottom of every page (put it in a reusable element) for the player bar. Inside, add an HTML element with an HTML5 audio element. Use custom states on the reusable element: 'now_playing' (Track), 'is_playing' (yes/no), 'playlist_queue' (list of Tracks). When a play button is clicked, set now_playing and use JavaScript to set the audio src and call play(). Add play/pause, next, previous buttons, and a progress bar.

1<audio id="audio-player" style="display:none;"></audio>
2<script>
3function playTrack(url) {
4  var player = document.getElementById('audio-player');
5  player.src = url;
6  player.play();
7}
8function pauseTrack() {
9  document.getElementById('audio-player').pause();
10}
11function togglePlay() {
12  var player = document.getElementById('audio-player');
13  if (player.paused) player.play(); else player.pause();
14}
15</script>

Create a 'My Playlists' page showing the user's playlists in a Repeating Group. Add a 'Create Playlist' button that opens a popup for name and optional cover image. On track listings, add an 'Add to Playlist' option that shows a dropdown of the user's playlists and adds the track to the selected playlist's tracks list. On the playlist detail page, show all tracks with a remove option and drag-to-reorder using a list management approach.

Add a heart/like button on every track and album card. Clicking it adds/removes the item from the user's library_tracks or library_albums list. Create a Library page with tabs: Liked Songs, Saved Albums, My Playlists. Each tab shows a Repeating Group of the user's saved items. The Liked Songs list doubles as an auto-generated playlist that can be played sequentially.

When a track starts playing, increment its play_count field (Make changes to Thing). Create a 'ListenHistory' Data Type with: user, track, played_at (date). Create a record each time a track plays. Use this data for: Recently Played section on the home page, personalized recommendations (most played genres/artists), and listening statistics on the user's profile.
