We'll be glad to make recommendations, but please... give us more information to work with. What is a gap?

Is this the time when the song's title page or graphic image is displaying?

Or is this a bootleg disc that had the graphic image removed?

Or did you make it with Karaoke Home Producer and forget to disable the Title Page when you are not using one?

Those are the only conditions I can think of that would generate a silence in the music before the lyrics begins.

Let us have some more info to work with.
