Spotify 9.1.0 vs 9.1.6 Class Comparison

Analysis Summary

✅ Classes that EXIST in BOTH versions:

  • SPTDataLoaderService - Core data loading (SAFE to hook)
  • NPVScrollViewController - Now playing view controller
  • NowPlaying_ScrollImpl.NPVScrollViewController
  • ContentOffliningUIHelperImplementation
  • Offline_ContentOffliningUIImpl.ContentOffliningUIHelperImplementation
  • PopUpPresentableContainer - Popup presentation container
  • EncoreConsumerMobile_Wrappers.PopUpPresentableContainer

❌ Classes REMOVED in 9.1.6:

  • Lyrics_NPVCommunicatorImpl.ScrollProvider - MISSING ❌
  • LyricsScrollProvider - MISSING ❌
  • $s26Lyrics_NPVCommunicatorImpl0A14ScrollProviderP - MISSING ❌
  • _TtC26Lyrics_NPVCommunicatorImpl14ScrollProvider - MISSING ❌

❓ Classes NOT FOUND in EITHER version:

  • SPTFreeTierArtistHubRemoteURLResolver - Doesn't exist in 9.1.0 or 9.1.6
  • SPTEncorePopUpContainer - Not found (but PopUpPresentableContainer exists)
  • SPTEncoreLabel - Not found in search

Lyrics Architecture Changes

9.1.0 Lyrics System:

  • Uses Lyrics_NPVCommunicatorImpl.ScrollProvider
  • Has LyricsScrollProvider protocol/class
  • Lyrics are integrated with Now Playing View

9.1.6 Lyrics System (NEW):

  • Completely different architecture
  • Uses Component-based UI system:
    • Components.UI.LyricsView
    • Components.UI.LyricsFullscreen
    • Components.UI.LyricsHeader
    • Components.UI.LyricsControlPanel
    • CanvasNowPlayingLyricsManager
    • CanvasNowPlayingLyricsView
  • New protobuf messages:
    • Com_Spotify_Lyrics_V2_LyricsRequest
    • Com_Spotify_Lyrics_V2_LyricsResponse
    • Com_Spotify_Colorlyrics_ColorLyricsResponse

Recommendations

For v6.2.10+ (Current Approach):

  1. Keep minimal mode active - Only hook SPTDataLoaderService
  2. Disable all lyrics for 9.1.x ✅ (Already done)
  3. Disable dark popups for 9.1.x ✅ (Already done)
  4. Disable track rows enabler for 9.1.x ✅ (Already done)

For Future Lyrics Support on 9.1.6:

To re-enable lyrics, would need to:

  1. Hook Components.UI.LyricsView instead of old classes
  2. Use CanvasNowPlayingLyricsManager for lyrics management
  3. Intercept Com_Spotify_Lyrics_V2_LyricsRequest/Response protobuf messages
  4. Work with the new Component-based UI system
  5. Likely requires significant rewrite of lyrics module

What Should Work in v6.2.10:

  • ✅ Basic premium patching via SPTDataLoaderService URL interception
  • ✅ No crashes from missing classes (all problematic hooks disabled)
  • ❌ No lyrics (architecture incompatible)
  • ❌ No dark popups (disabled for safety)
  • ❌ No artist hub track rows (class might not exist)

If v6.2.10 Still Crashes:

The crash would be from SPTDataLoaderService hook itself, which exists in both versions but might have different method signatures in 9.1.6.
