Describe the Bug

When playing a music video/the audio from a music video, there's sometimes some scenes before the actual song begin. Lets say you have used the regular YouTube client to discover music and found a song you then added to your playlist. You add the music video to it then. Later you play that playlist with Simpmusic. One such example is in the song "Can't hold us" by "Macklemore, Ryan Lewis". The first line is heard at 1:11, but the lyrics is already 1/3 into the song and doesn't match.

I believe it's because the database with the lyrics just don't know there's such thing as scenes before the actual music. Could it be possible to make something like, if it detects that it's a video, then offset the subtitles with x seconds. There are also a few songs with some scenes in between, where the actual song is "paused".

Steps to Reproduce
  1. Find a music video or just the audio of a music video with some scenes before the actual music
  2. Play it till the actual music starts
  3. Observe the wrong lyrics
Expected Behavior

The lyrics shows the correct line.

Research direction

Start by reproducing the reported example, “Can’t Hold Us” by Macklemore and Ryan Lewis, in the Android app and compare lyric timing with the video’s actual song start. Trace the lyrics synchronization and video playback entry points; done means lyrics align for videos with introductory or intervening scenes without regressing audio-only playback.
