Translating music lyrics is the hardest case for any dubbing tool. Songs have melody, rhythm, and rhyme that the translation has to compete with. SyncDub translates lyrics anyway, but the result is closer to a podcast than to karaoke.
What works
- Slow ballads — the dub has time to land.
- Spoken-word / rap with clear enunciation.
- Music videos where the song plays in the background of a narrative.
What doesn't
- Fast K-pop choruses — the dub can't keep up with the syllable rate.
- Operatic arias — the model flattens the dramatic dynamic range.
- Songs where the lyrics ARE the song (Beatles-style wordplay).
How to use SyncDub for music
- Open YouTube or Spotify Web Player (Spotify's web player doesn't expose audio to extensions — use YouTube Music instead).
- Click the SyncDub icon. Pick source and target language.
- Switch to 'background mode' — the dub plays at 30% volume so you can still hear the song.
Best songs to try
- BTS — 'Spring Day' — Korean ballad, clear enunciation.
- Bad Bunny — 'Ojitos Lindos' — Spanish reggaeton, the dub is decent.
- Cigarettes After Sex — 'Apocalypse' — slow English song, translated to Hindi works well.
