For real karaoke pick your song.instrumental.wav. For sing-along, the full mp4 is fine.
Pick song.vocals.wav to play original vocals quietly under the instrumental as a guide. Leave empty to skip.
Pick the original mp4 to see the music video while singing. Its audio is muted automatically — you'll hear only the instrumental + vocals mix.
Or paste timestamped lyrics directly above.
Negative = lyrics highlight earlier. Positive = later. YouTube caption timestamps often drift on real songs — you can also nudge this live while a song plays.
Mic not enabled yet — we'll ask when you start.
How do I get the transcript?
On the YouTube video page, click the "..." (more) under the video, choose Show transcript, then select all and copy. Paste it above. The lines look like a timestamp (0:00) followed by the words — Spotlight reads those timestamps to sync the highlighting. Auto-generated transcripts work but may be rough; creator-provided lyrics are cleaner.
