Metrolist v0.6.0 — Spotify Deep Integration

This release brings full two-way Spotify integration: edit playlists, reorder tracks, and sync your likes — all from within the app.

New Features

Bidirectional Like Sync with Spotify

• New "Sync Likes with Spotify" toggle in Spotify integration settings
• When enabled, every like/unlike action in the app (player, context menu, multi-select) is automatically synced to your Spotify Liked Songs
• On first activation, all your Spotify liked songs are imported and matched to their YouTube equivalents
• The local "Liked" playlist is replaced by your Spotify library — one source of truth

Edit Spotify Playlists from the App

• Add tracks to any of your Spotify playlists directly from song menus
• Works with both Spotify tracks (direct add) and YouTube tracks (automatic reverse lookup finds the Spotify match)
• Remove tracks from Spotify playlists with swipe-to-remove
• New playlist picker dialog for quick playlist selection

Sort & Refresh for Spotify Playlists

• Sort by: original order, name, artist, or duration
• Pull-to-refresh to reload playlists in real time
• Available in both Spotify playlists and liked songs screens

Drag-to-Reorder in Spotify Playlists

• Reorder tracks in your Spotify playlists via drag-and-drop
• Changes are synced to Spotify in real time via GraphQL
• Lock mechanism prevents accidental reordering
• Optimistic UI updates with server-side confirmation

Under the Hood

Spotify GraphQL Hash Audit

• Verified all 15 hardcoded GQL hashes against the current Spotify web player bundle
• Updated 5 rotated hashes: libraryV3, fetchPlaylist, queryArtistOverview, addToLibrary, removeFromLibrary
• Identified 2 at-risk hashes (searchDesktop, editPlaylistAttributes) not present in the current web player — functional for now but may require future attention

Architecture

• All like sync logic (YouTube, Spotify, Last.fm) is now centralized in SyncUtils and runs independently of YouTube login state
• SongEntity.toggleLike() handles local state only — remote sync is fully delegated to SyncUtils
